The assistive technology for dyslexia that K-12 schools actually deploy - TTS, STT, OCR, dictionary, and annotation - in one Chrome extension built for Google Workspace.
May 19, 2026
Assistive technology for dyslexia is any software or device that lowers the decoding load so students with dyslexia can access grade-level content without burning all their working memory on word recognition. Reading fatigue is the silent driver of underperformance: when decoding takes 80 percent of a learner's cognitive budget, comprehension, writing, and engagement all collapse. The right assistive technology for dyslexia rebalances that load.
The core categories are well-established: text-to-speech (TTS), speech-to-text (STT), optical character recognition (OCR) for images and PDFs, dictionary and vocabulary support, word prediction, and flexible text formatting. The Individuals with Disabilities Education Act (IDEA) requires schools to consider AT for any student whose IEP or 504 plan identifies a reading disability. For the wider context on identification, instruction, and accommodations, see our guide to dyslexia in K-12.
The foundational assistive technology for dyslexia. High-quality TTS lets students hear written text spoken aloud with natural prosody so comprehension is no longer gated by decoding. Look for human-like AI voices, adjustable speed, sentence-level highlighting, and one-click activation inside Google Docs, Slides, and the web.
Most curriculum lives in PDFs, and most PDFs are inaccessible to default screen readers. A dyslexia AT tool that reads PDFs aloud directly in the browser - including scanned and image-based PDFs - removes a huge barrier. Critical for science textbooks, worksheets, and any teacher-uploaded reading.
Slide decks, screenshots, and infographics often hide text inside images that TTS cannot reach. Optical character recognition (OCR) extracts that text on the fly so it can be read aloud. For dyslexic students this is the difference between participating in a science lesson and being locked out of it.
Word-level lookups reduce the cost of unfamiliar academic vocabulary, which is one of the biggest comprehension barriers for dyslexic readers. A built-in dictionary with simple definitions, example sentences, and translation into a home language supports both dyslexic students and dyslexic English learners.
Writing output is often years behind oral language for dyslexic students. STT lets them dictate ideas, answers, and drafts so spelling and handwriting do not gate expression. Look for accurate punctuation, dictation directly into Google Docs, and support for student-friendly voices and accents.
Dyslexic readers benefit from active strategies - highlighting, chunking, and annotating - that keep attention anchored to the page. Digital highlighting and note tools that work across Docs, PDFs, and the web give students a consistent, accessible way to mark up reading without needing a printed copy.
Start by listing every student with a dyslexia diagnosis, an IEP or 504 plan referencing reading, or an informal teacher referral. AT is required to be considered for any student whose plan identifies a reading disability, so the inventory becomes the rollout plan.
For each student, identify which AT categories matter most - TTS, STT, OCR, dictionary, word prediction, or formatting. Most dyslexic students need at least TTS plus one writing support (STT or word prediction). Document this in the IEP or 504 paperwork.
Prefer one Chrome extension that covers TTS, PDF read aloud, OCR, dictionary, and STT over five separate single-purpose apps. Fewer logins, less switching, and a far higher chance students will actually use it day-to-day.
Verify FERPA and COPPA compliance, any state-specific student data privacy requirements, and Google for Education Partner status. Get the tool added to the district's approved Chrome extension list before any rollout - this is the most common point of failure.
Run a 4-6 week pilot with one special education caseload or one grade level. Track which features students use, where adoption stalls, and which teachers need extra coaching. Capture written student feedback so accommodations teams can document impact.
Roll out school-wide with PD focused on dyslexia and AT - not just tool features. Teachers need to understand the why (decoding load, fatigue, working memory) before the how. Refresh the rollout each fall as new IEPs are written.
Schools comparing assistive technology for dyslexia typically evaluate Mote alongside Read&Write by Texthelp, ClaroRead, and NaturalReader. Each tool covers some of the core AT categories - TTS, STT, OCR, dictionary, and annotation - but they differ in breadth, pricing model, and how natively they live inside Google Workspace. Here is how they compare for a K-12 dyslexia use case.
For schools already standardized on Google Workspace and Chromebooks, Mote is the strongest fit because every core AT category for dyslexia ships in a single Chrome extension with district IT compliance baked in. Read&Write by Texthelp is the right call for schools heavily invested in the wider Texthelp ecosystem or those needing the deepest study-skills toolkit. ClaroRead is a fair choice for Windows-first districts. NaturalReader works well for individual learners and home use, especially when budget is tight, but is lighter on K-12 deployment features. Pick the tool that matches your device fleet and accommodation paperwork first, then check pricing.
Il n'existe pas de meilleure technologie d'assistance unique pour la dyslexie - la bonne combinaison dépend du niveau scolaire, de la gravité, et de savoir si l'obstacle provient de la lecture, de l'écriture ou des deux. La plupart des élèves ont besoin d'au moins quatre catégories : synthèse vocale, reconnaissance vocale, OCR pour les PDF et les images, et un dictionnaire ou une aide au vocabulaire.
Oui. La synthèse vocale est l'une des formes de technologie d'assistance les plus probantes pour la dyslexie. En convertissant le texte écrit en audio parlé, elle réduit la charge de décodage sur la mémoire de travail, permettant aux élèves de se concentrer sur la compréhension et d'accéder à un contenu de niveau scolaire au même titre que leurs pairs.
Cela varie. Certains outils, comme les fonctionnalités d'accessibilité Chrome de base et la saisie vocale Google, sont gratuits. La plupart des suites d'accessibilité complètes sont payantes, avec une tarification pour les écoles et les districts. Mote propose un essai de 30 jours pour les élèves et enseignants, avec des forfaits payants pour les déploiements à l'échelle de l'école et du district avec contrôles d'administration.
Oui. La plupart des technologies d'assistance modernes pour la dyslexie sont fournies sous forme d'extension Chrome, ce qui signifie qu'elles s'exécutent nativement sur les Chromebook et sur n'importe quel navigateur Chrome sur Mac ou Windows. Mote est une extension Chrome, donc les fonctionnalités d'assistance pour la dyslexie fonctionnent sur toute la flotte Chromebook sans installations supplémentaires.
Non. La technologie d'assistance pour la dyslexie est un complément, non un remplacement, à l'enseignement structuré de la littératie fondé sur la science de la lecture. La TA permet aux élèves d'accéder au contenu de leur niveau scolaire tandis qu'ils continuent à développer leurs compétences en décodage et en fluidité de lecture - les deux fonctionnent ensemble, pas l'un à la place de l'autre.
