Text to Speech for Dyslexia: What Helps and How to Set It Up on iPhone
What to look for in text to speech apps for dyslexia, how to set up read-aloud with highlighting on iPhone, and tips for school, work and books.
Updated September 27, 2026 · 6 min read
Text to speech lets you hear a text while your eyes follow it on the screen. Many people with dyslexia find that this combination makes reading less tiring and helps them keep the meaning, not just decode the words. Below: what to look for in a reading app, how to set it up on iPhone for free, and how to fit it into school, work and everyday reading.
Why hearing and seeing the text together helps
Dyslexia is a different way of processing written language, not a question of intelligence or effort. Often the hard part is decoding itself: it takes so much energy that less is left for meaning.
When a voice reads the text aloud, it carries the decoding, and your attention is free for the ideas. Research on reading while listening suggests it can support comprehension and vocabulary.
Seeing the words at the same time matters too: you still meet each word's spelling and stay connected to the page. That's why highlighting the spoken word or sentence is one of the most useful features.
A note on ADHD: many people with ADHD use text to speech for a related reason. A voice keeps a steady pace, so it's harder to drift off halfway down the page, and the highlight keeps your eyes anchored on the current line. If that sounds familiar, everything below applies to you too.
What to look for in a text to speech app for dyslexia
The features that make the biggest difference day to day:
- Word or sentence highlighting. The spoken text should be visibly marked so your eyes and ears stay together.
- Adjustable speed. Slower for new or dense material, faster for familiar texts.
- Readable display. Text size, line spacing, fonts and a comfortable theme (light, dark or warm), so lines are easy to track.
- Natural voices. A flat robotic voice gets tiring over a long chapter.
- Works with the files you actually get. PDFs, Word documents, EPUB books, web articles, printed worksheets.
- Tap to replay. Tap a sentence to hear it again.
- Remembers your place in long documents.
- Privacy. School reports and work documents are personal; ideally they're read on your device and not uploaded.
How to set up read-aloud on iPhone (free, built in)
Your iPhone already has a solid read-aloud toolkit.
Turn on Spoken Content with highlighting
- Open Settings → Accessibility → Spoken Content.
- Turn on Speak Selection. Now you can select text in any app and tap Speak in the menu.
- Turn on Speak Screen. Swipe down with two fingers from the top of the screen (or ask Siri "Speak screen") and the iPhone reads what's on the screen. A small controller appears with play/pause and speed.
- Turn on Highlight Content. Words or sentences are highlighted as they're spoken, in supported apps.
- Open Voices in the same menu and download a better voice for your language. Some are large downloads, so use Wi-Fi.
Listen to web pages and photos of text
- In Safari, open the page menu (the aA button or the page menu, depending on your iOS version) and tap Listen to Page to hear an article.
- With Live Text, you can select text in a photo in the Camera or Photos app. With Speak Selection on, a Speak option appears — handy for a printed handout.

Where built-in tools fall short
The built-in features are great for short texts. For longer reading, a few limits show up: Speak Screen reads whatever is on the screen, so it can include headers, page numbers and menus; it's designed for short sessions; it doesn't keep your reading position across documents; and the voices are the standard system voices.
Using a dedicated reader: setting up Aloudy
If you read long documents regularly, a dedicated reading app can make the routine smoother. Aloudy is an iPhone and iPad app built for this kind of focused reading. A setup that works well:
- Add your text. Open a PDF, EPUB, Word document, TXT or web page, paste text, or photograph a printed page — text recognition happens on the device.
- Pick a voice you like listening to. There are 46 neural voices in 32 languages. Try a few.
- Set the speed. Anywhere from 0.75× to 2×.
- Adjust the page. Choose a reading theme, font, text size and line spacing.
- Follow the highlight. The current sentence and word are highlighted as they're read. PDFs and EPUBs keep their original layout, with the spoken sentence highlighted right on the page.
- Tap to replay. Tap any sentence to jump to it or hear it again.
The app remembers where you stopped in each document, and PDFs and EPUBs have a table of contents and search. Voices run on the device, so once a voice is downloaded, reading works offline, and your documents never leave your phone. There's no account and no ads.
To be clear about the plans: the free version includes 5 voices and up to 500 characters per note, which is enough to try it on a page or a short text. Whole books and long PDFs need Aloudy Pro (monthly or a one-time lifetime purchase).
Everyday use cases
School reading. Load the assigned PDF or chapter, set a comfortable speed and follow along. Tap back to any sentence you want to hear again before writing notes. For worksheets on paper, take a photo and let it be read aloud. More on PDFs in how to read a PDF aloud on iPhone.
Work reports and email-length documents. Long Word files and meeting notes are easier to review when you listen and scan at once. Hearing your own writing read aloud also helps you catch missing words.
Books for pleasure. Free public-domain classics from Project Gutenberg and Standard Ebooks can be read with highlighting, and LibriVox offers free volunteer-read audiobooks. Libby lends audiobooks from public libraries if you have a library card.
Tips for parents and students
- Frame it as a tool, not a crutch. Listening while reading is how many people get through dense material efficiently. Using a read-aloud tool isn't "cheating" — it's a way to reach the content.
- Keep the eyes on the text. The benefit comes from hearing and seeing together.
- Start slower, then adjust. Speed can go up as the text becomes familiar.
- Let the reader choose the voice and theme. Having a say makes it more likely the tool gets used.
- Short sessions are fine. A focused session beats an hour of frustration.
- Talk to the school. Ask whether assigned texts are available as PDFs or e-books.
