Dyslexia Reading Tools: Apps and Devices That Make Text Accessible

Dyslexia affects an estimated 15-20% of the population, making reading slower and more effortful. Technology cannot cure dyslexia, but it can dramatically reduce the barriers it creates. Text-to-speech, specialized fonts, reading rulers, and immersive reader tools let dyslexic readers access information at the same speed as their peers.

Text-to-Speech Tools

Text-to-speech (TTS) is the single most impactful technology for dyslexic readers. Having text read aloud while following along visually reinforces word recognition and comprehension. Natural Reader, Voice Dream Reader, and the built-in TTS in iOS and Android all convert text to natural-sounding speech.

Microsoft Immersive Reader, built into Word, OneNote, Edge, and Teams, combines text-to-speech with syllable highlighting, line focus, adjustable spacing, and a picture dictionary. It is free and works on any platform through the Edge browser. This is the first tool every dyslexic user should try.

For students, Learning Ally provides human-narrated audiobooks of textbooks specifically for people with print disabilities, including dyslexia. Bookshare offers a massive library of accessible ebooks.

Dyslexia-Friendly Fonts

OpenDyslexic is a free font designed with weighted bottoms on letters to reduce rotation and swapping. It is available as a system font on most platforms and as an option in Kindle and Kobo e-readers. Studies on its effectiveness are mixed — some users report significant improvement while others see no difference.

Lexie Readable and Sylexiad are other dyslexia-friendly fonts. The key features are distinct letter shapes (b, d, p, q are clearly different), generous spacing, and consistent stroke weight. Try several fonts to find what works for you.

Reading Tools and Extensions

Browser extensions like BeeLine Reader color-code text lines with a gradient that guides your eyes from the end of one line to the beginning of the next, reducing line-skipping. Helperbird for Chrome adds dyslexia fonts, color overlays, line focus, and text spacing controls to any website.

Color overlays — placing a tinted transparent layer over text — help some dyslexic readers. The ReadingPhonics Color Overlay set provides physical overlays, while digital equivalents are available through browser extensions and reading apps. Common helpful tints include yellow, blue, and pink, but the effective color varies by individual.

E-Readers and Tablets

E-readers with dyslexia font support, adjustable spacing, and text-to-speech make reading books accessible. The Kindle Paperwhite supports OpenDyslexic font, custom line spacing, and wide margin settings. Kobo e-readers offer even more typographic control.

For academic reading, an iPad with Apple Pencil lets you annotate, highlight, and interact with text physically — many dyslexic readers comprehend better when they can mark up text. Apps like Notability and GoodNotes combine PDF reading with handwritten annotation.

Writing Support

Dyslexia affects writing as well as reading. Grammarly catches spelling and grammar errors that spell-check misses. Co:Writer uses topic-based word prediction to suggest words based on context rather than just first letters. Voice dictation (built into every platform) lets you compose text by speaking, bypassing the encoding challenges of dyslexia entirely.
