Text-to-speech software reads text aloud while highlighting it, which takes much of the decoding load off readers with dyslexia: a 2018 meta-analysis of 22 studies found a small-to-moderate average gain in reading comprehension (d = 0.35) for students with reading difficulties. The features that matter most are highlighting that follows the voice, adjustable speed, readable fonts and a tool that starts without friction. We compared nine options for Windows, Mac, iPhone and the browser, using their App Store listings, pricing pages and support documents as of October 2026, on those features and on the cost of long-term use. We make SpeakCove, so we've listed its limits too.

Buying Guide
Text Highlighting
Seeing each word or sentence highlighted as it's spoken links the sound to the text. Word-level highlighting is the most precise; sentence-level is less busy on the eye. Try both if you can.
Where You Read
On a Windows PC, Immersive Reader and Read&Write work inside the apps you already use. A web reader works on any computer without installing anything. On a phone, an app with a library keeps your place across long documents and books.
Low Friction
A reading aid should start right away. Sign-ups, ads, connection problems and crashes all add effort. Check whether a tool needs an account or internet before you rely on it.
Cost Over Years
Dyslexia is lifelong, so compare costs over years. Voice Dream's $79.99 a year is about $400 over five years and Read&Write's $184 a year is $920; a one-time unlock or a free built-in tool costs far less.
Speed and Fonts
Dense text may need a slower voice; familiar material can go faster. Readable fonts, spacing, Line Focus and background colors also help many readers.
The Verdict
SpeakCove is our pick if you want free, unlimited follow-along reading of your own documents: in any computer browser with all 10 voices, or on iPhone with sentence highlighting and no sign-up, as long as you keep the app open. On Windows, Microsoft's Immersive Reader in Word adds word highlighting, Line Focus and syllables at no extra cost. Read&Write ($184 a year) and Voice Dream ($79.99 a year) have the broadest sets of reading aids. If fonts and colors on iPhone matter most and you don't want to pay, start with Apple's built-in Accessibility Reader.
Try SpeakCove Free. No sign-up required. Start listening in seconds.

- What is the best free text-to-speech software for dyslexia?
- As of October 2026: on Windows, Read Aloud in Microsoft Edge reads web pages for free, and Immersive Reader, included with Word, highlights each word as it reads, splits words into syllables and has Line Focus; in any browser, SpeakCove's web reader at speakcove.com/text-to-speech, with 10 voices, no sign-up and no length limit; on iPhone, Apple's built-in Speak Screen and Accessibility Reader, or the free SpeakCove app for documents and books with sentence highlighting.
- How does text-to-speech help people with dyslexia?
- It takes over decoding, the step dyslexia makes hard, so you can spend your effort on meaning. A 2018 meta-analysis of 22 studies (Wood et al.) found a small-to-moderate average gain in reading comprehension (d = 0.35) for students with reading difficulties. In a 2026 eye-tracking study, junior high students with dyslexia read faster and with less effort using text-to-speech, while understanding about as much as when reading silently.
- What about speech-to-text (dictation) for dyslexia?
- Dictation is the writing-side counterpart, and good options are free: the microphone key on the iPhone keyboard, Windows key + H on a Windows PC, or Tools > Voice typing in Google Docs (in Chrome, Edge or Safari). Read&Write bundles dictation (Talk&Type) with text-to-speech and word prediction. SpeakCove only reads aloud; it doesn't do dictation.
- Is sentence highlighting or word highlighting better for dyslexia?
- Both help. Word-level highlighting gives precise tracking, which some readers prefer. Sentence-level highlighting gives more context and is calmer to look at. Try both to see which suits you.
- What features should I look for in text-to-speech software for dyslexia?
- Look for word or sentence highlighting, adjustable speed, readable fonts and a clean layout, on the device where you read most. Avoid tools that need a lot of setup, show ads, or stop working without internet.
- Can schools provide text-to-speech software as an accommodation?
- Yes. Many schools provide assistive technology through IEP or 504 plans. Read&Write is free for K-12 teachers, Voice Dream has a schools program, and Speech Central is free for schools that deploy it through Apple School Manager. Built-in tools like Apple's Speak Screen and Microsoft's Immersive Reader need no approval at all.
- Do I need the most expensive text-to-speech app for dyslexia?
- No. Highlighting and speed control matter most, and several free options include them. Natural AI voices can make long sessions more pleasant; whether that's worth a subscription depends on how much you read.
