Is Dragon NaturallySpeaking good for dyslexia?

Dragon can be a good choice for some people with dyslexia, particularly people who write a lot and want to train the software to their own vocabulary. The evidence is thinner than the marketing suggests. We found no controlled study that tests Dragon's dictation with students who have dyslexia, and the accuracy figures we checked come from other settings or older versions. For the wider picture, see our guide to speech to text for dyslexia and dysgraphia, part of our accessibility and health guides.

Dragon's features suit dyslexic writers: custom words and read-back

Several of Dragon's features map onto the problems dyslexic writers have. The most useful is training. Yale's dyslexia resource says that training words in Dragon strengthens your vocabulary and helps the software work more efficiently ¹. When Dragon mishears you because of its own error, Yale advises training the word by repeating it, so the software learns the correct pronunciation ². You can also add names, acronyms and phrases you use often. See custom vocabulary for how that works.

Read-back is the second feature. Nuance's help says that Read That lets Dragon read editable text aloud in a computer voice ³. Hearing a draft read aloud gives you a second check that does not depend on spelling, and it is the same routine described in our guide to speech to text for dyslexia.

Yale also gives a caution that matters for dyslexia. If your dyslexia affects how well you can read the training passages, Yale recommends that someone preview the challenging words with you before you train the software ⁴. Yale's reason is that the preview lets you read those words accurately when you train.

The evidence is about accuracy in other settings, not about dyslexic students

The one peer-reviewed accuracy figure we checked for Dragon comes from a 2000 study of physicians dictating medical reports. It found that Dragon NaturallySpeaking Medical Suite 3.0 had a vocabulary recognition error rate of 14.1 to 15.2 percent ⁵. That study used a medical vocabulary and an older engine, so it does not describe the current product or a student's essay. It is a reminder that accuracy depends on the vocabulary, the speaker and the setup.

Vendor material makes stronger claims, such as accuracy figures from Nuance's own pages. We treat those as marketing, because they are not independent studies and they do not separate dyslexia from other conditions. Yale's guidance is useful, but it is not a study of results either.

So the honest answer is that Dragon may help a particular writer, and you have to test it on your own speech and your own writing to find out whether it helps you.

Dragon's platform and price can rule it out before its features matter

Dragon's platform and price are often a bigger barrier than its features.

• Updates for the Mac version ended. Nuance said it would stop providing updates for Dragon Professional Individual for Mac after 22 October 2018 ⁶. If you use a Mac, read whether Dragon works on a Mac before you assume it is available.
• It is a paid product. A 2023 TechRadar review says Dragon Professional 16 is sold for a one-time fee of $699 for each license ⁷. Prices and editions change, so check the current listing before you buy. The question on whether Dragon is worth it covers the trade-offs in more detail.

It depends on your room, your speech and how much you write

• Background noise. Nuance tells users to reduce background noise, because Dragon hears and transcribes everything ⁸. A busy office or a shared classroom may cost accuracy, and the guidance does not say by how much.
• Volume. If you write a few notes a day, the built-in tools may be enough. If you write long documents every day, custom vocabulary and read-back are more valuable, and the cost is easier to justify.
• Speech. Dragon is trained on how you speak through its voice training. People who find reading the training passages hard should follow Yale's advice to preview the words first.
• Need. If your main problem is spelling, dictation helps by moving the spelling step to checking. If your main problem is word retrieval, a speech-language assessment may be the better first step, covered in can speech therapy help with dyslexia.

What to try before you buy Dragon

1. Use the built-in tools for a week. Start with the dictation that comes with your computer, and check its setup requirements before you rely on it at school or work. See how to dictate on Windows and voice to text on Mac.
2. Keep a log of errors you catch. Note which words were misheard and whether you caught them with read-back. That log shows whether a specialist tool would solve a real problem.
3. Test custom words. If you use names or technical terms, add a few and see whether the software learns them. The glossary entry on Dragon NaturallySpeaking explains the product in more detail.
4. Compare other dictation apps before you commit. Yap, which we make, is an on-device dictation app for Mac and Windows, and it is a fair option to compare. Its current price is on our pricing page. Choose by how well it handles your speech, not by the brand.

If you are not sure whether dictation suits you, read speech to text for dyslexia, which covers the research and the read-back routine in full.
