What's the difference between text-to-speech (TTS) and a screen reader?

Text-to-speech (TTS) and screen readers are two technologies that were developed to help individuals who are blind or have low-vision access digital content. While both technologies read text out loud, there are some key differences between them. Learn how to use both and explore additional Windows 11 accessibility features with this guide.

What is text-to-speech (TTS)?

Text-to-speech (TTS) technology converts written text into spoken words. It’s typically used to provide audio feedback in apps, narrate e-books out loud, create audio versions of written content, and more. TTS systems can be used with various applications and devices, such as smartphones, computers, and even cars.

What are screen readers?

Screen readers are software programs that read screen text and other screen elements aloud. They use their operating system's accessibility features to access the text, then read it out loud with a natural-sounding voice. Screen readers can also provide other forms of feedback, including audio cues and vibration, to help individuals navigate the page.

What’s the difference between screen readers and TTS?

One of the key differences between TTS and a screen reader is their customization options. Most TTS software lets users choose from a variety of voices and adjust the tone of the speech. Screen readers offer a much wider range of personalization options, including the ability to adjust the narrator’s voice and speech rate, punctuation, language, and much more.

Windows 11 accessibility features

Windows 11 includes several built-in accessibility features, including the screen-reading app Narrator. The current version of Narrator includes support for more languages, better performance, and improved navigation. Windows 11 accessibility features also include:

Voice recognition

Windows 11 voice recognition technology allows users to control their computer using voice commands, which is particularly useful for people who require mobility assistance.

Magnifier

The magnifier tool in Windows 11 was designed to help people with low vision see the content on their screen more clearly. Recent improvements include more options for customizing the zoom level and the display’s color contrast.

Live captions

Windows 11 live captions automatically transcribe any audio content, including audio from the microphone, for individuals who are deaf or hard of hearing.

Immersive Reader

This learning feature removes digital clutter on the page to help readers focus on the text. Customization options include the ability to change spacing, zoom, color, and more.
