Dictation for tremor, Parkinson's, MS and ALS: what to set first
By Ryleigh Newman · Published · Updated
Dictation for tremor, Parkinson's, MS or ALS on a Mac starts from the typing problem, not the diagnosis: a hand that lands on the wrong key, a hand that tires, a voice that has gone quiet. Each section below names the YapToText setting for one of those problems. I am not a clinician, and nothing here is medical advice.
My hands make typing difficult, and I built YapToText so dictation could stand in for the keyboard on a Mac. People write to me with a condition in the subject line and a typing problem in the body, so this page is organized by the problem. It makes no promises: the speech model is Whisper, a general-purpose model that I have not tuned for any condition. The app is free with no trial clock, so the honest test is five minutes in your own room with your own voice, and the last section is exactly that.
Everything runs on the Mac, and nothing you say is uploaded, which matters when what you are dictating is about your own health. The privacy page has the detail.

How to read this page
Each section is named for a condition because that is what people search for, but what it describes is a typing problem: keys that get mis-hit, a hand that tires, a voice that is hard to hear. If your condition is not listed, find the problem that matches, and the settings are the same. Cerebral palsy, muscular dystrophy and Ehlers-Danlos come up below, under the problem rather than the name.
I describe how the app is operated. I do not say what it will do for you, because I cannot know that. How well dictation works for one voice can only be found out by using it. Two things hold for every section: nothing mentioned here is locked behind a payment, and speech, cleanup and history all stay on the Mac, with no network use except a model download you start yourself. The accessibility hub covers VoiceOver, Voice Control and dictating with no pointer at all, and this page does not repeat it.
Tremor and Parkinson's: mis-hit keys and a soft voice
This section covers two problems: a hand that lands on the wrong key, and a voice that has got quieter. There is a setting for each.
The keys
Dictation starts on one tap of one key, never a chord. Right Command is the default, and any key can take its place, so pick the one your hand lands on reliably and never types with. Space and the number keys are captured only while a dictation is running, and a double press of the dictation key while the app is finishing is ignored, so it cannot throw away the result. Turn on Require pressing Escape twice to cancel, in the Keys card of the Dictation page, and a cancel needs a second press within 0.6 seconds. Even when a stray press does cancel, the dictation is still transcribed and saved to History, marked as canceled, and never inserted. The same one-key rule is what I would set for cerebral palsy or any spasticity that makes a two-key combination impossible. The keys and shortcuts page lists every key the app watches.
The voice
Auto-amplify quiet speech measures your voice against the room rather than a fixed level, and it is on by default. If the Mac's own input volume is low, the app says so and offers to raise it. Input boost, in Settings, General, Microphone, adds gain by hand: raise it until normal speech reaches the green-to-yellow zone of the meter without sitting in the red. And the app watches how well it hears you: if the signal drops well below your own normal, the Dictation page says so and names the likely cause. The troubleshooting guide has the order I check things in.
To judge the result, open History after a dictation and choose Show pipeline details. It puts the raw transcript, what the speech model heard, next to the cleaned text. Read the raw transcript, and decide for yourself. Whisper is a general-purpose speech model, and nothing I built tunes it for a voice that has changed.
MS and fatigue: good days and bad days
With fatigue, the problem may not be that typing is impossible. It may be that it is impossible today. So use the app on the days typing is hard and the keyboard on the days it is not. There is no subscription, so a week without a single dictation costs nothing, and there is nothing to pause or cancel.
The dictation key works two ways, chosen on the Dictation page. Tap to start / stop needs two short taps and no holding. Hold to talk records only while the key is down, which suits a short thought and a hand that would rather not tap twice. Pick whichever the day allows. On a heavy day, Auto-stop after silence makes it one press: start, talk, and stop talking. The Quick Edit key has the same tap or hold choice.
On a laptop, Switch models with the power source, on the Energy page, gives the dictation model and the cleanup model each a plugged-in choice and an on-battery choice. It is off by default, and the energy page has the details.
When a sentence comes out wrong, Quick Edit fixes it by voice: select it, press the Quick Edit key, say the change, and the rewrite replaces the selection in place. Retyping a sentence is the thing a tired hand should not have to do. The Quick Edit page lists what you can say.
ALS, muscular dystrophy and progressive weakness
When strength is changing, the question is whether the app can follow. The trigger is a key, and how it fires is a setting, so moving from tapping to holding, or from one key to another that is easier to reach, is a change on the Dictation page and not a change of app. If a switch or another device presses a key for you, that key can be the trigger, because the app only watches for a key. I have not tested every switch interface, so that describes how it works, not a guarantee. The one-key dictation guide has a ten-second test.
After a dictation lands, in Settings, Advanced, Text output, presses Return or Command Return in the apps you choose, the moment your words land, so a dictated message or prompt goes out without another press. It is per app, so turn it on only where you want it. When moving around the Mac gets hard too, Apple's Voice Control clicks, scrolls and opens apps by voice, and YapToText is built to work alongside it.
History keeps each dictation on the Mac with its raw transcript, the final text and, by default, the audio, and any entry can be played back. If the app or the Mac dies mid-sentence, the audio survives: at the next launch the app transcribes it, puts the text on your clipboard, and files it in History as Recovered after a crash. The History page covers how long entries are kept.
One thing that is not mine. Apple's Personal Voice lets you record your voice while you still have it, so the Mac can speak what you type in a synthesized voice that sounds like you. Apple says it needs a Mac with Apple silicon and works in English (U.S.), Mandarin Chinese (China mainland) and Spanish (Mexico). It lives in System Settings, Accessibility, Speech, and YapToText has no connection to it. I mention Personal Voice because people ask me, not because the app uses it.
Stroke, one working hand, limb difference
With one working hand the keyboard is not gone; it is half as wide. Put the dictation key on the side that hand reaches. For a left hand, Left Control, Left Option, Fn and Caps Lock all work, and so does any letter or F-key on that side; Left Command and Left Shift are the two keys the trigger field will not take. For a right hand, Right Command, the default, already sits there.
Corrections go through Quick Edit rather than the keyboard: select the sentence, press the Quick Edit key, say the change. For key combinations in other apps, macOS has Sticky Keys, which lets you press modifier keys one at a time instead of all at once. It is Apple's, in System Settings, Accessibility, Keyboard, and it is worth turning on whether or not you use my app.
Aphasia is different, and I want to be plain about it. Dictation transcribes what is said. If the difficulty is finding the word, the app cannot help with that part. It types what comes out; it does not supply the word.
Arthritis, neuropathy and hands that hurt
With numb fingers, the trouble can be that the letters come out wrong and you cannot feel that they did. My rule is simple: anything longer than a line gets dictated, and the keyboard is for the odd character.
A wrong word in something you just dictated is fixed by voice: right after it lands, dictate replace X with Y as the whole next dictation, within 30 seconds. Fix the same mishearing twice and the app offers to remember it, so it is right from then on; the Dictionaries page explains how an entry works. Longer fixes go to Quick Edit: select the sentence and say the change.
If the problem is pain rather than numbness, from arthritis, Ehlers-Danlos or any joint that objects to a long stretch at the keys, the same rule holds: dictate the long things and let the keyboard do the short ones. The app does not care why your hands need a break. The carpal tunnel guide shows how to set it up so no key is held down while you talk.
Unclear or slurred speech
This is the section where I have to be most careful. Whisper, the speech model in the app, is a general-purpose model, and nothing I built changes how it handles speech that is hard to understand. The audio work I did is for quiet voices and noisy rooms, not for dysarthria. If your speech is significantly affected, test before you rely on it.
Climb this ladder, smallest step first:
- Slow down slightly and move closer. Put the microphone nearer your mouth, or yourself nearer the Mac.
- Read the microphone rating. In Settings, General, Microphone, say a few words: the app rates how clearly it hears you, from Excellent to Needs attention, and says what to change.
- Test in Raw Transcription. Dictate a paragraph in Raw Transcription, which types exactly what the model heard with no cleanup to cover for it, and read the result. The Modes page covers Raw Transcription.
- Teach the words it keeps missing. If the same word comes out wrong the same way every time, a dictionary entry fixes it, and your dictionary also shapes what the speech model hears, not just what it types.
A consistent mishearing is what dictionaries are for; a random one is not. If the test shows more errors than you can live with, a tool built specifically for impaired speech is the better answer, and I would rather say that here than have you spend an afternoon finding out. Those tools exist. Mine is not one of them.
The five-minute test
Five minutes, three checks, and an honest answer at the end.
Step 1: Install it and grant both permissions
- You: Install YapToText from the Mac App Store on an Apple silicon Mac with macOS 14 or later, allow the microphone, and switch it on under System Settings, Privacy & Security, Accessibility.
- YapToText: Shows each as Granted on the welcome screens, and the Get set up card leaves its Home page once both are on.
- Check: Both show as granted. Without Accessibility it still transcribes, but copies the result to the clipboard; the install guide walks through both.
Step 2: Hear the model on its own
- You: Click into a note, start a dictation, press 2 for Raw Transcription, its place in the default order, and say one paragraph in your ordinary voice.
- YapToText: Types exactly what the speech model heard, with basic punctuation and no AI cleanup.
- Check: Read it. That is the model on its own, with nothing to cover for it.
Step 3: Compare with Auto mode, then fix one sentence by voice
- You: Say the same paragraph again in Auto mode, then select one sentence of the result, tap the Quick Edit key and say one change, such as make it shorter.
- YapToText: Cleans up the second dictation, then replaces your selection with the edit.
- Check: In History, Show pipeline details on each entry puts what was heard next to what was delivered.
Then decide. If it is not for you, delete the app, and everything it stored goes with it. There is no trial clock, no account and nothing to cancel.
The short version
- Start from the problem. Mis-hit keys, tired hands and a quiet voice each have a setting.
- Keep it to one key. Tap or hold, any key, and change it as your hands change.
- Test before you rely on it. Raw Transcription and History show exactly what was heard.

Questions
Does dictation work with a hand tremor on a Mac?
It can, because it needs far fewer key presses than typing. In YapToText one tap of one key starts and stops it, Space and the number keys only count during a dictation, and you can require two presses of Escape to cancel. Whether it suits your hand is a five-minute test, and the app is free.
Will YapToText understand slurred speech?
I cannot promise it. The speech model is Whisper, a general-purpose model I have not tuned for speech that is hard to understand. Raw Transcription shows exactly what was heard, so a five-minute test with your own voice gives an honest answer.
Is there dictation software for ALS on a Mac?
Yes. Voice Control and Dictation are built into macOS, and YapToText is a free dictation app whose trigger can move from tapping to holding to another key, or to a switch that presses one, as strength changes. I have not tested every switch interface, so test yours first.
Is there a subscription I waste on the weeks I cannot use it?
No. YapToText is free with no paid tier and no account, so a week without a dictation costs nothing and there is nothing to pause or cancel.
Can a message be sent without touching the keyboard?
Yes. In Settings, Advanced, Text output, add an app under After a dictation lands and choose Press Return or Press Command Return. That key is pressed the moment your words land, so the message goes out on its own.
Is what I dictate about my health private?
Yes. Speech and cleanup run on the Mac, and the only network use is a model download you start yourself. History stays in the app's own folder on your Mac, where you choose how much is kept and can delete any entry with its audio.
