Standard TTS vs. Neural TTS

Before diving into the world of text to speech, here’s a quick look at the difference between standard and neural text to speech tools.

• Standard TTS is the older approach to text to speech software. If you think of artificial, stiff-sounding text to speech audio, you’re thinking of standard TTS.
• Neural TTS draws on neural network technology or AI to generate more natural-sounding, humalike speech. Don’t let that creep you out, though – neural TTS can create truly lifelike and listenable audio that cuts out a major chunk of time for businesses and creators, helping you reach more people with your content.

What is text-to-speech technology (TTS)?

By The Understood Team

Expert reviewed by Jamie Martin

At a glance

Text-to-speech (TTS) technology reads aloud digital text — the words on computers, smartphones, and tablets.

TTS can help people who struggle with reading.

There are TTS tools available for nearly every digital device.

Text-to-speech (TTS) is a type of assistive technology that reads digital text aloud. It’s sometimes called “read aloud” technology.

With a click of a button or the touch of a finger, TTS can take words on a computer or other digital device and convert them into audio. TTS is very helpful for kids and adults who struggle with reading. But it can also help with writing and editing, and even with focusing.

TTS works with nearly every personal digital device, including computers, smartphones, and tablets. All kinds of text files can be read aloud, including Word and Pages documents. Even online web pages can be read aloud.

Dive deeper

How does text-to-speech work.

The voice in TTS is computer-generated, and reading speed can usually be sped up or slowed down. 

Many TTS tools highlight words as they are read aloud. This allows the user to see text and hear it at the same time.

Some TTS tools can also read text aloud from images. For example, a user could take a photo of a street sign on their phone and have the words on the sign turned into audio.

Learn about the different types of TTS built into mobile devices.

The connection to audiobooks

You might be wondering what the connection is between TTS and audiobooks.

TTS is a tool that reads text aloud. An audiobook is a recording of a book read by a human voice (or created by TTS). Sometimes, people say TTS or audiobooks to mean the same thing.

Learn about how your child may be eligible for free audiobooks .

Types of text-to-speech tools

There are many different TTS tools:

Built-in text-to-speech: Many devices have built-in TTS tools . This includes desktop and laptop computers, smartphones, digital tablets, and Chromebooks. 

Web-based tools: Some websites have TTS tools on-site. 

Text-to-speech apps: Users can download TTS apps on smartphones and digital tablets. There are also TTS tools that can be added to web browsers, like Chrome .

Text-to-speech software programs: Many literacy software programs for desktop and laptop computers have TTS.

Find a list of free online assistive technology tools .

How text-to-speech can help kids

Print materials in school — like books and handouts — can create barriers for kids with reading challenges. That’s because some kids struggle with decoding and understanding words on the page. Using digital text with TTS can help.

Since TTS lets kids both see and hear text when reading, it creates a multisensory reading experience. And like audiobooks, TTS won’t slow down the development of kids’ reading skills.

The Best Speech-to-Text Apps and Tools for Every Type of User

You don't need to use your fingers when you can type by talking with the best dictation software we've tested. It's fast, easy, and helps people who otherwise can't type.

Our team tests, rates, and reviews more than 1,500 products each year to help you make better buying decisions and get more from technology.

• Best Text-to-Speech Tools
• Best Transcription Services

Table of Contents

Typing isn't easy or even possible for everyone, which is why you might prefer to talk. Speech-to-text software, also sometimes called dictation software, makes it possible, by turning what you say into typed text.

Speech-to-text software is different from voice control software, although some apps do both. Voice control is the accessibility feature that lets you open programs, select on-screen options, and otherwise control your device using only your voice. Both macOS and Windows have voice control included. It's called VoiceOver on macOS and Speech Recognition in Windows.

Don't confuse speech-to-text software with transcription software , either, even if the categories overlap. Transcription software is typically for transcribing meetings or recordings, sometimes of multiple people, and generally after the fact. Dictation software, meanwhile, is a way to use your voice to type in real time. You talk to your computer or mobile device and immediately see the words on the screen. You can add punctuation by saying the name of the punctuation out loud—for example, "period," "comma," or "open quote" and "end quote."

Speech-to-text features or apps also should not be confused with text-to-speech tools , sometimes known as screen readers, which read text on the screen to you aloud.

Recommended by Our Editors

Most people don't need to install software to dictate text to their computer or phone. That's because every major operating system has a speech-to-text feature built in, and they work about as well as anything else on the market. Here we point out where to find these features on your device, and talk about a powerful commercial product with more features, should you need to do more with a speech-to-text tool than the built-in options offer.

Best Speech-to-Text Tool for Windows

Windows Speech, often referred to as voice typing, was among the most accurate tools I tested for this article. Both Windows 10 and Windows 11 come with Speech, which you can try out using the keyboard shortcut Windows Key-H anywhere you can type. Up pops a window with a microphone icon. Tap the microphone and start talking. Text shows up more or less in real time. 

You can add punctuation manually using commands , or you can try the experimental auto-punctuation feature. As a writer, I prefer adding punctuation manually—I'm pretty particular about my punctuation—but the automated feature worked fairly well and I could imagine it being good enough for some people. See our complete guide to learn more about using speech recognition and dictation in Windows .

Best Speech-to-Text Tool for Microsoft Office

You can dictate text in Microsoft Office by clicking the prominent Dictate button in all versions of Word, Powerpoint, OneNote, and Outlook. This brings the excellent engine Microsoft offers all Windows users, complete with the auto-punctuation feature, to just about every major operating system—the web, Android, iOS, and macOS versions of Office all include this dictation feature. It's great news if you use one of those systems and don't love the built-in speech-to-text engine.

Best Speech-to-Text Tool for macOS

Apple has included Dictation in macOS since 2012. To enable the feature, head to System Settings > Keyboard and scroll down to Dictation, where you can also set a keyboard shortcut. Newer Macs have a dedicated function key that looks like a microphone (F5) to enable and disable dictation in the top row of the keyboard. The speech detection is very accurate and shows up in near real time. You can add punctuation with spoken commands . Potentially incorrect words are underlined in blue after you're done with dictation, and you can right-click or Command-click on them to see other potential options, similar to how spellcheck works. Note that Apple silicon Macs can do dictation for the most common languages offline, whereas Intel Macs send audio to Apple servers for processing.

Best Speech-to-Text Tool for Apple Mobile Devices

Dictation (Mobile)

If you use the default keyboard on the iPhone and iPad, there's a microphone icon to the left of the space bar (as shown in the image) or sometimes below the space bar on the right side, that you can tap to use dictation. It works almost exactly the same as on macOS. Tap that microphone key and a microphone icon will show up next to your cursor. Start talking and your text will appear. You can add punctuation and formatting using spoken commands , just like on the Mac. The text recognition is accurate, the same as on the Mac.

Best Speech-to-Text App for Android

Android's default keyboard, Gboard, also has a built-in dictation feature . Tap the microphone in the top-right corner of the keyboard and start talking. It works in any Android app where you can type text, and the recognition is quite accurate. You can add punctuation with spoken commands, like saying "comma" and "period," just like on other systems.

Best Speech-to-Text Tool for Google Docs

Google Docs Voice Typing

Google Docs has a built-in dictation feature called Voice Typing . Google says it only works if you're using the Chrome browser, but by observation it works in Microsoft Edge and perhaps other Chromium-based browsers. Click Tools > Start voice typing and a large microphone icon appears, which you can click to start talking. Punctuation and formatting is handled by voice commands . Recognition works about as well as Gboard, which makes sense—they're likely using the exact same engine.

Most Powerful Speech-to-Text App

Dragon Professional

Dragon is one of the most sophisticated speech-to-text tools. You use it not only to type using your voice but also to operate your computer with voice control. Dragon Professional, the most general version, isn't cheap at $699. A mobile-only version, Dragon Professional Anywhere, is a $15-per-month subscription with a one-week free trial. Additional versions of the software are available for use by legal, health care, and law enforcement professionals, with a focus on understanding the specialized language in those sectors. If you need a business-grade speech-to-text tool that's more powerful than the default software that comes with your operating system, Dragon is worth looking into.

A thought is only as useful as how you express it. One way people express their ideas is through text: ideas made readable. Whether with feather pens and parchment or through today’s instant SMS messages, text has always been a powerful documentation and communication tool.

Another way to give life to ideas is through speech: ideas made listenable. For a time, the human voice was the only way to facilitate speech. But today, machine learning and artificial intelligence (AI) enable devices and applications to replicate a human voice’s unique tones.

Text-to-speech (TTS) and the meaning of TTS technology is as simple as it sounds: technology that reads text aloud with an automated voice. Many devices and applications today offer TTS. It’s useful for listeners with visual impairment or language-based learning disabilities and can increase efficiency by allowing employees to multitask. In other words, TTS is a powerful productivity tool for organizations everywhere.

Here, we’ll cover how text-to-speech works, TTS tool types, and 3 ways TTS can benefit your business.

How does text-to-speech work?

Reading and inputting text are the most common ways users interact with applications and services on text-to-speech devices, such as desktop computers, smartphones, and tablets. If a Word doc, SMS message box, or web browser offers TTS capabilities, users can press a button or vocalize a command to convert text into computer-generated speech.

Some TTS technology tools allow the user to customize aspects of the program’s voice like:

• Reading speed

Other TTS technology offers multiple premade voices or reads in a distinctive voice—like Apple’s Siri, Amazon's Alexa, and the TikTok caption reader. Some photo applications also use a technology called optical character recognition to read aloud text found in images or video.

Types of TTS tools

Programs and services have myriad uses for TTS technology. As such, there are many different TTS tool types available on the market. In this section, we’ll explore some of the most commonly used types of TTS tools:

• TTS tools for operating systems (our friend, Siri, for instance) convert written text into spoken words across many types of digital content.
• TTS tools for applications add functionality to improve the user experience and expand accessibility. For instance, e-reader apps, like Amazon Kindle or Google Play Books, offer TTS that reads many digital books aloud.
• TTS applications like NaturalReader and Narrator’s Voice convert inputted text into automated speech with added features like pitch shifting, language translation, gender swapping, and audio file conversions to download and share.
• TTS tools for the web can read aloud text found throughout a website—serving as a virtual assistant for a person with visual impairment or translating a video’s speech into a different language, for instance. Companies can pay for this service to enhance website accessibility or individual users may opt for a similar service provided by companies like Google.

As you can see, there’s no one size fits all with TTS. You can choose one or more TTS tools depending on what makes the most sense for your organization. Next, we’ll get into specific use cases to help you narrow down the best solution.

Business use cases for TTS

Text-to-speech helps businesses create more engaging and accessible content that meets the needs of customers and employees alike. Here are 3 of the most common business use cases for TTS:

1. Multitasking

Say a colleague sends an SMS message containing the information you need for today’s big meeting, but you’re on the go. Messages are difficult to read while walking—especially through crowded spaces—and unsafe to read while driving. But stopping to read the message is cumbersome and time-consuming. What do you do?

Text-to-speech lets you pay attention to your primary task—like commuting, writing, or sketching—while listening to text converted into speech from your device. This empowers you to be safer and more aware of your surroundings without sacrificing productivity.

2. Visual impairments

People with visual impairments may struggle or be unable to read a device’s text. Others with eyestrain or computer vision discomfort may find exposure to screens uncomfortable. With text-to-speech, they can listen to text rather than burden themselves to read it.

Of course, screen visibility issues can impact everyone. For instance, when glares hinder a reader’s ability to read from their mobile device outside, TTS can vocalize on-screen text so they don’t have to find shade or increase the screen brightness. TTS, therefore, helps people make the most of their devices.

3. Translations

Language barriers can slow or halt business meetings, presentations, and day-to-day operations. For instance, when an organization’s international branch sends a document written in its native language, it can be costly and time-consuming to translate that business-crucial content.

Today, text-to-speech enables fast translation of foreign text into live speech that single receivers and groups alike can hear and understand. This streamlines your workflows by allowing your organization to focus less on logistical challenges from language barriers and more on initiatives that drive business growth. TTS can also help you deliver digital presentations to diverse stakeholders all around the world.

What is text to speech?

• 4 contributors

In this overview, you learn about the benefits and capabilities of the text to speech feature of the Speech service, which is part of Azure AI services.

Text to speech enables your applications, tools, or devices to convert text into human like synthesized speech. The text to speech capability is also known as speech synthesis. Use human like prebuilt neural voices out of the box, or create a custom neural voice that's unique to your product or brand. For a full list of supported voices, languages, and locales, see Language and voice support for the Speech service .

Core features

Text to speech includes the following features:

More about neural text to speech features

Text to speech uses deep neural networks to make the voices of computers nearly indistinguishable from the recordings of people. With the clear articulation of words, neural text to speech significantly reduces listening fatigue when users interact with AI systems.

The patterns of stress and intonation in spoken language are called prosody . Traditional text to speech systems break down prosody into separate linguistic analysis and acoustic prediction steps governed by independent models. That can result in muffled, buzzy voice synthesis.

Here's more information about neural text to speech features in the Speech service, and how they overcome the limits of traditional text to speech systems:

Real-time speech synthesis : Use the Speech SDK or REST API to convert text to speech by using prebuilt neural voices or custom neural voices .

Asynchronous synthesis of long audio : Use the batch synthesis API to asynchronously synthesize text to speech files longer than 10 minutes (for example, audio books or lectures). Unlike synthesis performed via the Speech SDK or Speech to text REST API, responses aren't returned in real-time. The expectation is that requests are sent asynchronously, responses are polled for, and synthesized audio is downloaded when the service makes it available.

Prebuilt neural voices : Azure AI Speech uses deep neural networks to overcome the limits of traditional speech synthesis regarding stress and intonation in spoken language. Prosody prediction and voice synthesis happen simultaneously, which results in more fluid and natural-sounding outputs. Each prebuilt neural voice model is available at 24 kHz and high-fidelity 48 kHz. You can use neural voices to:

• Make interactions with chatbots and voice assistants more natural and engaging.
• Convert digital texts such as e-books into audiobooks.
• Enhance in-car navigation systems.

For a full list of platform neural voices, see Language and voice support for the Speech service .

Improve text to speech output with SSML : Speech Synthesis Markup Language (SSML) is an XML-based markup language used to customize text to speech outputs. With SSML, you can adjust pitch, add pauses, improve pronunciation, change speaking rate, adjust volume, and attribute multiple voices to a single document.

You can use SSML to define your own lexicons or switch to different speaking styles. With the multilingual voices , you can also adjust the speaking languages via SSML. To improve the voice output for your scenario, see Improve synthesis with Speech Synthesis Markup Language and Speech synthesis with the Audio Content Creation tool .

Visemes : Visemes are the key poses in observed speech, including the position of the lips, jaw, and tongue in producing a particular phoneme. Visemes have a strong correlation with voices and phonemes.

By using viseme events in Speech SDK, you can generate facial animation data. This data can be used to animate faces in lip-reading communication, education, entertainment, and customer service. Viseme is currently supported only for the en-US (US English) neural voices .

We plan to retire the traditional/standard voices and non-neural custom voice in 2024. After that, we'll no longer support them.

If your applications, tools, or products are using any of the standard voices and custom voices, you must migrate to the neural version. For more information, see Migrate to neural voices .

Get started

To get started with text to speech, see the quickstart . Text to speech is available via the Speech SDK , the REST API , and the Speech CLI .

To convert text to speech with a no-code approach, try the Audio Content Creation tool in Speech Studio .

Sample code

Sample code for text to speech is available on GitHub. These samples cover text to speech conversion in most popular programming languages:

• Text to speech samples (SDK)
• Text to speech samples (REST)

Custom neural voice

In addition to prebuilt neural voices, you can create custom neural voices that are unique to your product or brand. All it takes to get started is a handful of audio files and the associated transcriptions. For more information, see Get started with custom neural voice .

Pricing note

Billable characters.

When you use the text to speech feature, you're billed for each character that's converted to speech, including punctuation. Although the SSML document itself isn't billable, optional elements that are used to adjust how the text is converted to speech, like phonemes and pitch, are counted as billable characters. Here's a list of what's billable:

• Text passed to the text to speech feature in the SSML body of the request
• All markup within the text field of the request body in the SSML format, except for <speak> and <voice> tags
• Letters, punctuation, spaces, tabs, markup, and all white-space characters
• Every code point defined in Unicode

For detailed information, see Speech service pricing .

Each Chinese character is counted as two characters for billing, including kanji used in Japanese, hanja used in Korean, or hanzi used in other languages.

Model training and hosting time for custom neural voice

Custom neural voice training and hosting are both calculated by hour and billed per second. For the billing unit price, see Speech service pricing .

Custom neural voice (CNV) training time is measured by ‘compute hour’ (a unit to measure machine running time). Typically, when training a voice model, two computing tasks are running in parallel. So, the calculated compute hours are longer than the actual training time. On average, it takes less than one compute hour to train a CNV Lite voice; while for CNV Pro, it usually takes 20 to 40 compute hours to train a single-style voice, and around 90 compute hours to train a multi-style voice. The CNV training time is billed with a cap of 96 compute hours. So in the case that a voice model is trained in 98 compute hours, you'll only be charged with 96 compute hours.

Custom neural voice (CNV) endpoint hosting is measured by the actual time (hour). The hosting time (hours) for each endpoint is calculated at 00:00 UTC every day for the previous 24 hours. For example, if the endpoint has been active for 24 hours on day one, it's billed for 24 hours at 00:00 UTC the second day. If the endpoint is newly created or suspended during the day, it's billed for its accumulated running time until 00:00 UTC the second day. If the endpoint isn't currently hosted, it isn't billed. In addition to the daily calculation at 00:00 UTC each day, the billing is also triggered immediately when an endpoint is deleted or suspended. For example, for an endpoint created at 08:00 UTC on December 1, the hosting hour will be calculated to 16 hours at 00:00 UTC on December 2 and 24 hours at 00:00 UTC on December 3. If the user suspends hosting the endpoint at 16:30 UTC on December 3, the duration (16.5 hours) from 00:00 to 16:30 UTC on December 3 will be calculated for billing.

Personal voice

When you use the personal voice feature, you're billed for both profile storage and synthesis.

• Profile storage : After a personal voice profile is created, it will be billed until it is removed from the system. The billing unit is per voice per day. If voice storage lasts for a period of less than 24 hours, it will be billed as one full day.
• Synthesis : Billed per character. For details on billable characters, see the above billable characters .

Text to speech avatar

When using the text-to-speech avatar feature, charges will be incurred based on the length of video output and will be billed per second. However, for the real-time avatar, charges are based on the time when the avatar is active, regardless of whether it is speaking or remaining silent, and will also be billed per second. To optimize costs for real-time avatar usage, refer to the tips provided in the sample code (search "Use Local Video for Idle"). Avatar hosting is billed per second per endpoint. You can suspend your endpoint to save costs. If you want to suspend your endpoint, you can delete it directly. To use it again, simply redeploy the endpoint.

How to use Google text-to-speech on your Android phone to hear text instead of reading it

• You can use Google 's text-to-speech feature to do things like help you hear grammatical oddities in your text or documents.
• Before you can use it, however, you'll have to enable the feature on your phone.
• Here's what you need to do to enable and use Google   text-to-speech on your Android device.
• Visit Business Insider's homepage for more stories .

Speech-to-text is a popular productivity hack that many use to more quickly and easily create written sentences. 

Its counterpart, text-to-speech , can help with productivity too, albeit in a different way: By hearing the text read back to you in a robotic voice, you may be able to catch skipped words, grammar mistakes, and awkward phrasing.

Here's what you need to know to start using text-to-speech on your Android :

Check out the products mentioned in this article:

Google pixel 3a (from $399.99 at best buy), how to enable google text-to-speech.

1. Go into your device's settings.

2. Tap "Accessibility."

3. Depending on your device, you may need to tap "Vision."

4. Choose "Select to speak."

5. Toggle the feature on and confirm by tapping "Ok" in the pop-up window.

Depending on your device, you will either see a circle pop-up with the text-to-speech icon, or it will appear in the lower-right corner of your screen.

How to use Google text-to-speech

Once you've set up the feature and you've navigated to a bit of text you want to have read back to you, here's what you'll need to do:

1. Tap the text-to-speech icon — you'll see a red stop button appear, with a greyed-out play button next to it.

2. Tap and select the speech you want read back to you. Drag your finger across the screen if there is more than one section, or press the play button to have everything on the screen read back to you, including button commands.

3. Tap the play button to begin the text-to-speech playback.

Text-to-Speech Tools for Education: Speechify Vs. ReadSpeaker

Not sure how to pick between Speechify and ReadSpeaker text to speech for your education needs? Learn which is best for your students here.

Since its 2017 debut, text-to-speech (TTS) app Speechify has risen high in the rankings of both iOS and Android app stores. By doing so, it’s become more visible to educators at every level.

But how does the Speechify app stack up against an established TTS leader that specializes in education TTS? In other words, how does Speechify compare to ReadSpeaker for Education ?

ReadSpeaker has been at the forefront of TTS technology for over 25 years, and the team understands the value of TTS for education. That’s why ReadSpeaker offers a series of plug-ins and tools specifically for educators and learners.

Rather than a single mobile app, ReadSpeaker provides a complete TTS solution for every learning scenario. That includes TTS integrations with learning management systems (LMSs), assessment platforms, content-creation apps, and proctoring solutions. It also includes reading, writing, and studying tools that work in tandem with lifelike TTS.

Speechify and ReadSpeaker for Education do bring some common capabilities to the education market:

✓ Both TTS providers offer text-to-speech software for a broad range of scholastic use cases: digital accessibility, alternative formats for learning materials, automated textbook narration, and more.

✓ Both have high-quality, natural-sounding voices that leverage the power of artificial intelligence—and that students enjoy hearing.

✓ Both support many different languages and offer competitive pricing.

✓ Both enhance TTS with student-friendly functionality like audio file downloads and reading speed control.

One serious difference, however, is that Speechify’s focus is on a TTS app for general consumer audiences. ReadSpeaker builds comprehensive TTS solutions—much more than a mobile app—for educational institutions and their students.

In other words, only ReadSpeaker supports TTS all the time, for every student, on any device, and in any learning context.

Here’s how that difference plays out in the functionality of the Speechify text-to-speech app and ReadSpeaker’s many TTS solutions for education.

ReadSpeaker Vs. Speechify in Education: Contrasting TTS Capabilities

✓ Works via user-facing consumer apps and requires an internet connection

✓ Lifelike, natural-sounding voices in 30+ languages

✓ User-friendly interface

✓ Enhances TTS with options to adjust voice selection, font size, and reading speed, plus text highlighting

✓ Best suited for personal use as a productivity/efficiency tool

✓ Integrates with Canvas, Gmail, Google Drive, iCloud, Dropbox, Microsoft One Drive

✓ Offers an API for content creators who want to make Speechify available for site visitors

✓ OCR component allows audio generation from images

✓ Cloud-based TTS limits user control over data security

✓ Automatically collects user information, including location, log, usage, and device data

✓ Online and offline deployment options; can run on your school IT office’s server or desktops, or be embedded into learning devices of any size

✓ High-quality, natural-sounding voices in 50+ languages, from Arabic to isiZulu.

✓ Easy to use across any content students access

✓ Enhances TTS with the same tools as Speechify, PLUS additional tools that support learning needs including dictionary lookup, translation, simple view, and more

✓ Works well for students, families, educators, and administrators to improve accessibility

✓ Integrates deeply with LMS platforms and web content, including all proctoring software and cloud-based education platforms, making it ideal for institutional use

✓ Designed for students, educators, and instructional designers who want to create an accessible, speech-enabled platform

✓ Reliable tech and linguistic support for the lifetime of your product

✓ On-premise, API, and server-based solutions available for heightened institutional security

✓ No user data collection, in compliance with GDPR, FERPA, CIPA, and student data privacy policies

Speechify operates on a software-as-a-service (SaaS) model. Its streaming text to speech runs through a variety of online AI text-to-speech apps, including:

• Speechify Chrome Extension
• Speechify iOS App
• Speechify Android App
• Speechify Microsoft Edge Add-On
• Speechify Text to Speech Web App
• Speechify AI Studio

Note that these apps may integrate with web browsers—but they don’t work seamlessly within your LMS. That means students have to open extra apps to use TTS, which creates a barrier known to depress usage of helpful learning tools.

Education-software developers can also get Speechify TTS through an API, and the company offers special packages for educators. You can run Speechify on Windows or Mac, and on an iPhone, iPad, or Android device. Their voices are comparable to those offered by Amazon Polly TTS.

User-facing consumer apps are the core of Speechify’s offerings, however, and all their cloud-based TTS solutions require an internet connection. With Speechify’s premium version, you can download speech files. That’s the only way students can use TTS offline with Speechify.

ReadSpeaker has a lot more deployment options—both online and off. Streaming TTS products from ReadSpeaker include:

• ReadSpeaker for Education  (TTS for HTML, OCR, documents, etc)
• ReadSpeaker TextAid (AT with TTS and reading/writing tools)
• SpeakUp (offline reading)

Unlike Speechify, ReadSpeaker solutions can also run on your school’s private server. They can run on an educator, administrator, or student’s desktop. Instructional designers can even embed ReadSpeaker TTS into original educational devices.

ReadSpeaker’s on-premise solutions are the gold standard in data security; after all, attackers have a hard time accessing systems that don’t connect with the open internet!

This advanced security helps those companies that need to keep sensitive training materials ring-fenced, or to protect learner data, bringing ReadSpeaker tools into compliance with the Family Educational Rights and Privacy Act (FERPA), the Children’s Internet Protection Act (CIPA), and the U.S. Department of Education’s student privacy policies .

With ReadSpeaker, schools can also run TTS on their private servers; within the institution’s IVR systems; in custom educational applications; on school desktops; or on teaching devices. This is possible thanks to offline ReadSpeaker solutions including:

• ReadSpeaker speechServer (server-based TTS)
• ReadSpeaker speechServer MRCP (standards-based TTS for IVR systems)
• ReadSpeaker speechEngine SDK (desktop/application-based TTS)
• ReadSpeaker speechEngine SDK Embedded (offline TTS that runs on any device)

ReadSpeaker also offers real-time text-to-speech solutions for educational game developers. These TTS game-engine integrations help developers make more accessible educational games and digital training systems in leading platforms like Unity and Unreal Engine.

Speechify Voice Cloning Vs. ReadSpeaker Custom AI Voices for Educators

Custom AI voices allow educators to create new voices for their learning content. In the field of corporate learning, a custom voice supports audio branding in training materials.

Both Speechify and ReadSpeaker offer such custom TTS voices. But they arrive at these solutions in very different ways.

• Speechify provides a self-service voice-cloning app . The app records the user speaking, then generates a synthetic version of that speaker’s voice.
• ReadSpeaker creates custom TTS voices to meet any need. Our team of speech scientists and AI engineers use special recordings from trained actors (or a chosen representative) to train an original AI voice model.

Speechify’s voice-cloning app works quickly. It can clone a voice with as little as 30 seconds of data.

But in an AI model, limited data leads to limited quality. ReadSpeaker’s white-glove approach ensures a lifelike final product. It also gives corporate learning professionals more control over their (literal) brand voice. Rather than simply cloning a speaker, ReadSpeaker can create a composite voice that expresses brand personality in precise detail.

There are also ethical concerns surrounding self-service voice cloning software. Few safeguards prevent users from using Speechify’s app to clone a voice without the speaker’s permission.

At ReadSpeaker, we generate our own training data under contract with all stakeholders. We build AI ethics into our business model, ensuring users get great TTS voices that won’t create legal or reputational risk—an essential consideration for schools and corporate training departments alike.

ReadSpeaker has a long history of specialization in TTS solutions for education and corporate learning . As we’ve mentioned, we offer seamless TTS integrations with all major learning management systems . This is a key point of comparison with Speechify, which, rather than providing controls within the LMS, introduces yet another app students have to open.

Opening apps—or even new browser tabs—can be a stumbling block for learners with dyslexia, learning disabilities, visual impairments, or unfamiliarity with the language. ReadSpeaker’s LMS compatibility simplifies student access to TTS for greater ease of use.

Finally, ReadSpeaker offers ongoing linguist support to ensure perfect pronunciation—even for the specialized vocabulary of a science course. Speechify doesn’t match this support. Let’s take a closer look at this distinction.

Speechify and Pronunciation Accuracy

No text-to-speech engine can pronounce everything perfectly, every time. There are simply too many variables in language: homographs, proper nouns, technical jargon, acronyms, etc.

That means TTS engines need ways to update mispronounced terms as they arise.

Speechify’s only apparent means of correcting mispronunciations is for users to retype words phonetically, using Wikipedia’s pronunciation respelling key .

This is an ad hoc approach that doesn’t really fix the problem.

ReadSpeaker and Pronunciation Accuracy

ReadSpeaker doesn’t just offer a TTS app; we build ongoing partnerships with educators. Pronunciation assistance is a big part of that relationship.

At ReadSpeaker, we provide custom pronunciation dictionaries. Add a term and the TTS engine will pronounce it perfectly forever. In other words, you fix the problem once, and it stays fixed.

If you run into any trouble, our speech scientists will be happy to help. The ReadSpeaker team ensures perfect pronunciation for any use case, including highly technical subjects rife with complex terminology.

How Educators Choose Between ReadSpeaker for Education and Speechify

ReadSpeaker for Education and Speechify have a lot of benefits in common. They both offer a browser extension that reads websites aloud, enhancing the learner’s reading experience considerably. They both offer a document reader that can handle ePub, PDF files, and Google Docs.

They both have hundreds of voice options and very high speech quality. They both offer a student-friendly interface for TTS control. Not surprisingly, you’re likely to find either topping a “best text-to-speech” list.

The bottom line is this:

If you’re looking for a TTS mobile app to audio-enable social media pages, online tutorials, or other casual text, Speechify might be the right choice. It offers a limited free version as well as paid plans. (Some user reviews report charges during the free trial, difficulty canceling the service, and dissatisfaction with high prices.)

Text-to-Speech Technology: What It Is and How It Works

Text-to-speech (TTS) is a type of assistive technology that reads digital text aloud. It’s sometimes called “read aloud” technology. TTS can take words on a computer or other digital device and convert them into audio. TTS is very helpful for kids who struggle with reading, but it can also help kids with writing and editing, and even focusing.

Text-to-speech (TTS) is a type of assistive technology that reads digital text aloud. It’s sometimes called “read aloud” technology.

With a click of a button or the touch of a finger, TTS can take words on a computer or other digital device and convert them into audio. TTS is very helpful for kids who struggle with reading. But it can also help kids with writing and editing , and even focusing.

TTS works with nearly every personal digital device, including computers, smartphones and tablets. All kinds of text files can be read aloud, including Word and Pages documents. Even online web pages can be read aloud.

The voice in TTS is computer-generated, and reading speed can usually be sped up or slowed down. Voice quality varies, but some voices sound human. There are even computer-generated voices that sound like children speaking.

Many TTS tools highlight words as they are read aloud. This allows kids to see text and hear it at the same time.

Some TTS tools also have a technology called optical character recognition (OCR). OCR allows TTS tools to read text aloud from images. For example, your child could take a photo of a street sign and have the words on the sign turned into audio.

Print materials in the classroom — like books and handouts — can create obstacles for kids with reading issues. That’s because some kids struggle with decoding and understanding printed words on the page. Using digital text with TTS helps remove these barriers.

And since TTS lets kids both see and hear text when reading, it creates a multisensory reading experience. Researchers have found that the combination of seeing and hearing text when reading:

• Improves word recognition
• Increases the ability to pay attention and remember information while reading
• Allows kids to focus on comprehension instead of sounding out words
• Increases kids’ staying power for reading assignments
• Helps kids recognize and fix errors in their own writing

Like audiobooks, TTS won’t slow down the development of your child’s reading skills.

Kids learn in different ways and at different paces.

It’s important to teach to each student’s individual strengths, skills and needs. This is true for all kids — not just kids with learning and attention issues.

7 Things to Know About the 1 in 5 with Learning and Attention Issues

Depending on the device your child uses, there are many different TTS tools:

• Built-in text-to-speech: Many devices have built-in TTS tools . This includes desktop and laptop computers, smartphones and digital tablets and Chrome. Your child can use this TTS without purchasing special apps or software.
• Web-based tools: Some websites have TTS tools on-site. For instance, you can turn on our website’s “Reading Assist” tool, located in the lower left corner of your screen, to have this webpage read aloud. Also, kids with dyslexia may qualify for a free Bookshare account (opens in a new window) with digital books that can be read with TTS. There are also free TTS tools available online (opens in a new window) .
• Text-to-speech apps: Kids can also download TTS apps on smartphones and digital tablets. These apps often have special features like text highlighting in different colors and OCR. Some examples include Voice Dream Reader, Claro ScanPen and Office Lens.
• Chrome tools: Chrome is a relatively new platform with several TTS tools. These include Read&Write for Google Chrome and Snap&Read Universal. You can use these tools on a Chromebook or any computer with the Chrome browser. See more Chrome tools to help with reading (opens in a new window) .
• Text-to-speech software programs: There are also several literacy software programs for desktop and laptop computers. In addition to other reading and writing tools, many of these programs have TTS. Examples include Kurzweil 3000, ClaroRead and Read&Write. Microsoft’s Immersive Reader tool also has TTS. It can be found in programs like OneNote and Word. See more examples of software for kids with reading issues (opens in a new window) .

It’s a good idea to start the conversation with your child’s teacher if you think your child would benefit from TTS. If your child has an Individualized Education Program ( IEP ) or a 504 plan, your child has a right to the assistive technology she needs to learn. But even without an IEP or a 504 plan, a school may be willing to provide TTS if it can help your child.

You can also use TTS at home. Try one of the tools above, or check out options for free audiobooks and digital TTS books (opens in a new window) . And learn more about assistive technology for reading .

• Text-to-speech (TTS) can provide a multisensory reading experience that combines seeing with hearing.
• Using TTS won’t delay the development of your child’s reading skills.
• Your child’s school can provide TTS, but you can also try it at home.

Voice   Generator

This web app allows you to generate voice audio from text - no login needed, and it's completely free! It uses your browser's built-in voice synthesis technology, and so the voices will differ depending on the browser that you're using. You can download the audio as a file, but note that the downloaded voices may be different to your browser's voices because they are downloaded from an external text-to-speech server. If you don't like the externally-downloaded voice, you can use a recording app on your device to record the "system" or "internal" sound while you're playing the generated voice audio.

Want more voices? You can download the generated audio and then use voicechanger.io to add effects to the voice. For example, you can make the voice sound more robotic, or like a giant ogre, or an evil demon. You can even use it to reverse the generated audio, randomly distort the speed of the voice throughout the audio, add a scary ghost effect, or add an "anonymous hacker" effect to it.

Note: If the list of available text-to-speech voices is small, or all the voices sound the same, then you may need to install text-to-speech voices on your device. Many operating systems (including some versions of Android, for example) only come with one voice by default, and the others need to be downloaded in your device's settings. If you don't know how to install more voices, and you can't find a tutorial online, you can try downloading the audio with the download button instead. As mentioned above, the downloaded audio uses external voices which may be different to your device's local ones.

You're free to use the generated voices for any purpose - no attribution needed. You could use this website as a free voice over generator for narrating your videos in cases where don't want to use your real voice. You can also adjust the pitch of the voice to make it sound younger/older, and you can even adjust the rate/speed of the generated speech, so you can create a fast-talking high-pitched chipmunk voice if you want to.

Note: If you have offline-compatible voices installed on your device (check your system Text-To-Speech settings), then this web app works offline! Find the "add to homescreen" or "install" button in your browser to add a shortcut to this app in your home screen. And note that if you don't have an internet connection, or if for some reason the voice audio download isn't working for you, you can also use a recording app that records your devices "internal" or "system" sound.

• Text-to-speech (TTS) assistive technology: Best tools

Recent research shows TTS apps are effective in learning

Choosing the right assistive technology tools: what to look for, how to get started: speechify.

Technology is improving our quality of life every day. Here’s how to choose the best text-to-speech assistive technology tools for your needs!

Text-to-speech ( TTS ) assistive technology: Best tools

Text-to-speech apps are software that turn text into speech. Most of them use OCR-based technology (optical character recognition). This means that they can recognize characters in text documents as well as pictures and turn them into  speech.

At their core, these are assistive apps. They can help people with learning disabilities like dyslexia to enjoy the content that would previously be almost impossible for them. On the other hand, they also allow us to listen to articles and text documents while multitasking with other activities like driving or doing chores.

To get the most out of your text-to-speech experience, it’s necessary to try different tools before you can choose the perfect one. Luckily, they’re a dime a dozen. Many of them are also free, which is a great way to familiarize yourself with the tech before spending your hard-earned money. But don’t worry—you don’t have to try all of them. Follow along as we explain how to pick a TTS tool that will suit your needs the best.

Getting the most out of text-to-speech

There are many reasons people use text-to-speech software. Yet, only a few do it just for fun. As such, to get the most out of them, it’s essential to have a purpose. One common reason to use a TTS app would be if you had a learning disability like dyslexia or a visual impairment that restricts you from reading and writing. Luckily, with the use of a TTS app, one can easily overcome such obstacles.

Another common purpose for the use of TTS software would be to enjoy your favorite book while doing something else that requires your full attention. For example, if you’re driving, you can paste your book into the app, and it will read the text aloud to you . The same goes for any other activity that restricts you from reading. Multitaskers delight in turning everything they can think of into audiobooks!

Aside from overcoming reading difficulties and entertainment, these software programs are useful to get in touch with the latest technology. After all, in a day and age of constant tech development, it’s easy to find yourself behind. So, we’d recommend getting on the text-to-speech tool bandwagon sooner rather than later. TTS apps are now commonplace in video production, improving website accessibility, creating memes, and more.

In the last couple of years, several studies explored how text-to-speech technology affects students. All of them were conducted in a similar pattern. Two groups of students were formed, with one group given TTS software to assist them in overcoming educational material—and a control group without. The results were unanimous. Students without text-to-speech tools would provide far worse results than those with software like Speechify and its alternatives.

But these studies didn’t just focus on the improvement of students’ reading skills. Instead, they would also suggest that TTS apps help learners better understand words, and concepts, as well as motivate them to keep learning. This was especially evident for students with learning disabilities like dyslexia, visual impairments, brain injuries, and emotional instabilities. As such, it’s safe to assume that text-to-speech apps are the future of special education.

Before you can start to enjoy turning the written word into speech, you need to consider two main things. First, not all TTS tools are compatible with your device, operating system, and web browser. You should, therefore, research if the software you’re looking to use has a version for your smartphone or computer, as well as the web browsers you use (Chrome, Safari, Microsoft, etc.).

On the other hand, what are you looking for in a text-to-speech application? Is it for educational or entertainment purposes? The thing is, not all TTS software programs will suit both needs. This is why it’s essential to choose the right one. Luckily for you, a screen reader like Speechify checks all the boxes—from versatility to user-friendliness to performance.

Best new assistive technology tools

• Speechify: Speechify is the answer to all your text-to-speech-related needs. It’s a high-end piece of software that uses OCR, machine learning, and advanced AI to turn what you read into speech on all platforms. The versatility of Speechify is above all other TTS tools, as well as its easy-to-use interface. It can help with learning difficulties, dictation, and making school literature way more engaging and fun. The lifelike voices, customization options, and accessibility across platforms and devices simply can’t be beat!
• Voice Dream : Voice Dream reader is a popular piece of TTS software. It gets the job done for both students with learning disabilities and people who generally enjoy listening more than reading. Still, Voice Dream does have its downsides. It isn’t free, and it’s also only available for iOS platforms and Android. There isn’t a version for Windows-based computers.
• Wideo : Although primarily a video-creating platform, Wideo offers text-to-speech services, too. This is one of the features that sets it apart from other software of its kind out there. It’s an easy-to-use tool that pretty much gets the job done for TikTok users. But since it’s not a TTS tool at its core, the audio might sound a bit lifeless compared to other options.
• Nextup: TextAloud from Nextup is another popular TTS tool on the market. It’s a solid companion for everyone using Windows-based computers, as it works particularly well with Microsoft Word as well as web pages. It also comes along with productivity and proofreading tools. The only issue with it is that it isn’t available for iPhones, iPads, and other Apple products, as well as Android mobile devices.
• Azure Text to Speech : Azure is Microsoft’s very own answer to TTS technology, and it offers a range of features for its users. It advertises itself as having lifelike speech as well as fully customizable voices. Additionally, you can fiddle with audio controls such as speed, pitch, and pauses. Still, as it’s a Microsoft product, Azure isn’t available for Mac and Apple smartphones.
• Google Cloud Text-to-Speech: Next up, we need to mention Google’s text-to-speech application. It’s a great match for anyone using the Google Chrome browser on an Android device or a PC. This app includes support for numerous languages and is a reliable pick for anyone on a tight budget. Still, there’s a certain limit of monthly characters that it can read for free. Otherwise, you’ll have to pay to use it in an unlimited fashion.
• Amazon Polly : Similarly to the above-mentioned TTS programs, Amazon Polly is a proper tool to turn text into speech. It’s uses OCR technology, as well as machine learning, that can make your reading easier. There’s a free version of Amazon Polly, but it doesn’t provide many options. Hence, if you’re looking for high-quality features to overcome dyslexia, it might not be a perfect choice for you.

OCR, AI, and machine learning are what makes Speechify accomplish numerous tasks. Nevertheless, there are several ways that you can use this TTS application. It’s versatile, and that’s what makes it stand out from the rest.

To get started, you’ll need to download the appropriate version for your device. It works on iOS operating systems, as well as on Android smartphones. On the other hand, if you’re looking to use it on a computer, you can also install the macOS or Windows version.

Once you install it on your device, you can run any text through it by simply pasting it into the application. Then again, if you want Speechify to read aloud another format (e.g., a photo) you can do that as well, thanks to some OCR magic.

Speechify is among the best read&write programs out there, and you’ll see that immediately once you download it. It will increase your reading skills, and concentration levels, as well as make you fall in love with old books that you simply don’t have the time to read. So what are you waiting for? Check out Speechify and all the things you can do with it now!

Title: t3m: text guided 3d human motion synthesis from speech.

Abstract: Speech-driven 3D motion synthesis seeks to create lifelike animations based on human speech, with potential uses in virtual reality, gaming, and the film production. Existing approaches reply solely on speech audio for motion generation, leading to inaccurate and inflexible synthesis results. To mitigate this problem, we introduce a novel text-guided 3D human motion synthesis method, termed \textit{T3M}. Unlike traditional approaches, T3M allows precise control over motion synthesis via textual input, enhancing the degree of diversity and user customization. The experiment results demonstrate that T3M can greatly outperform the state-of-the-art methods in both quantitative metrics and qualitative evaluations. We have publicly released our code at \href{ this https URL }{ this https URL }
