Speech to Text for Dyslexia: Write by Talking, Not Spelling

Dyslexia can turn writing into two jobs at once: working out what you want to say, and working out how to spell it. Speech to text for dyslexia takes most of the second job away. You say the sentence, and LumeVoice types it into whatever app you're using, with spelling, punctuation and filler words already handled.

Why writing takes so much effort with dyslexia#

The International Dyslexia Association (IDA) updated its definition in 2025. It describes dyslexia as a specific learning disability marked by difficulties with word reading and/or spelling, in accuracy, speed or both (IDA definition). IDA says perhaps as many as 15–20% of people have some symptoms, including slow or inaccurate reading, poor spelling, poor writing and mixing up similar words, and it stresses that dyslexia isn't due to a lack of intelligence or of desire to learn (IDA, Dyslexia Basics).

For adults, the NHS lists signs such as often spelling words wrong and feeling tired after a lot of reading and writing (NHS). On a keyboard that tiredness builds, because every hard word is a small decision: guess, check, fix, or swap it for a word you know you can spell. Red underlines appear while you're still thinking, and it's easy for your attention to go to the mistakes instead of the idea.

Talking skips that loop. You say the word you actually mean, and the software works out how it's spelled.

How speech to text helps when spelling is the hard part#

Basic dictation writes down what it hears. LumeVoice adds a cleanup step, so a spoken first draft comes out readable:

• Spelling and grammar are fixed as the text is written, so there's less to correct afterward.
• Punctuation, capitals and paragraph breaks are added from context. You can also say "comma", "new line" or "new paragraph".
• Filler words such as "um", "uh" and "you know" are removed, along with stutters.
• Changes of mind are applied: "send it Tuesday, actually Wednesday" becomes "Send it Wednesday."
• Spoken lists come out as numbered or bulleted lists.
• Names and jargon you add to the custom dictionary on Mac or Windows come out spelled the way you spell them.

Here's the kind of thing you might say, and what lands in the email (an illustration, not a test result):

You say: "um hi Dana, so I looked at the the schedule and I can do the training on Tuesday, actually Wednesday, and I'll bring the handouts"

LumeVoice types: "Hi Dana, I looked at the schedule and I can do the training on Wednesday. I'll bring the handouts."

The ideas and the wording stay yours. The cleanup tidies how the text reads; it doesn't add points you didn't make.

How to set up LumeVoice for writing with dyslexia#

On a computer. Download LumeVoice for Mac or Windows. Click where you want to write, hold fn on a Mac or Ctrl + Win on Windows, talk, and let go: the text appears at your cursor. For a longer stretch, double-press the key to go hands-free, then press it once when you're done. A small pill above the Dock or taskbar shows a waveform while it listens and a check mark when your text lands.

On a phone. On iPhone, switch to the Lume keyboard in any app and talk. On Android, tap the floating bubble that sits over your keyboard; your usual keyboard stays put for everything else.

Teach it your words. In the Mac or Windows app, add the names and terms you use most to the custom dictionary: colleagues and classmates, course or product names, the street you live on. They're passed to speech recognition, so they come out spelled right.

Save repeated text as snippets. Say a short cue and Lume types the full text, such as your email sign-off, your address or a link you share often. That's one less long string to spell each time.

A dyslexia-friendly routine: talk the first draft, then edit#

Writing and correcting at the same time slows drafting down. Split the two:

1. Say the plan first. Dictate three or four bullet points covering what the piece needs to say. Understood.org suggests starting with an outline before writing with dictation (Understood).
2. Talk one paragraph at a time. Hold the key, explain the first point as if to a friend, and let go. Whole sentences work better than single words, because the surrounding words help speech recognition pick the right one.
3. Don't stop to fix. Keep going until the draft is down. The filler words and restarts get cleaned up for you.
4. Listen to it. If rereading is tiring, have your device read the draft aloud. On Mac, iPhone and iPad this is Read & Speak (called Spoken Content on older versions); Word has Read Aloud on the Review tab, Microsoft Edge has Read aloud, and Android has Select to Speak.
5. Fix what sounds wrong. Use the keyboard for small changes, or select a sentence and dictate it again.
6. Check the usual suspects. Names, numbers and words that sound alike (their and there, flour and flower) are where any dictation tool is most likely to guess wrong.

The routine is the same in Google Docs and Microsoft Word. LumeVoice types into the document the way a keyboard would, so there's nothing to install inside either one.

Is built-in speech to text enough?#

Your devices already come with free dictation, and for short messages it may be all you need. Here's how the main options compare, as of October 2026:

The built-in tools are improving, and it's worth knowing where they're strong. Apple's Dictation on iPhone works without an internet connection in many languages, lets you edit by voice, and with iOS 27 the newest iPhones also tidy spelling, punctuation and capitalization in English. On Copilot+ PCs, Windows' Fluid dictation corrects grammar, punctuation and filler words in English.

If you mostly write in one app, start with what's built in, and if you need dictation without an internet connection, Apple Dictation on iPhone is the one to try. LumeVoice earns its place when you write a lot, across many apps and devices, and want the same cleanup, dictionary and snippets everywhere.

What speech to text can't do for dyslexia#

• It doesn't read text aloud. LumeVoice writes; it isn't a text-to-speech tool or a screen reader. Pair it with your device's built-in reader from step 4 above.
• It doesn't teach reading or spelling. IDA notes that most people with dyslexia need help from a teacher, tutor or therapist trained in a structured, multisensory approach. Dictation helps you write in the meantime; it isn't a replacement for that support.
• It can still mishear. Names, rare words and soundalikes need a check, and a noisy room or a poor microphone makes any dictation less accurate.
• Editing is a keyboard-and-mouse job. LumeVoice types; it can't select, move or delete text by voice command, and Understood.org notes that editing a document by dictation can be hard anyway. If you need to control your whole computer by voice, Voice Control on a Mac and voice access in Windows 11 are built for that.
• It needs an internet connection. LumeVoice is cloud-based, so it won't work without one.
• It won't write for you. It turns what you say into clean text. The ideas, and the final read-through, are yours.

How to get the accessibility discount#

LumeVoice gives 50% off Pro to anyone who finds typing hard because of a disability, injury or health condition, and dyslexia counts.

1. Email hello@lumevoice.com with a one-line request.

Either way, you can try LumeVoice first with 3,000 free words, no card required, and the accessibility page explains how the discount works.

The short version#

If spelling is what slows your writing down, try saying the first draft instead of typing it. Plan out loud, talk one paragraph at a time, listen back, then fix. LumeVoice handles the spelling, punctuation and "ums" on the way, and the ideas stay yours.
