How to dictate on a Mac, and keep doing it
Turning dictation on takes about two minutes. Getting past the first awkward week takes four specific habits. This guide covers both, starting with the free option already on your Mac.

Start with what is already installed
Do not buy anything yet. Every Mac has dictation built in, and a week with it will tell you more about whether speaking suits you than any review.
- Open System Settings → Keyboard Scroll to Dictation and switch it on. macOS may download a language pack; let it finish.
- Read the line beneath the toggle It tells you, for your language, whether your voice is processed on the Mac or sent to Apple's servers. This varies by language and region, and that sentence is the only authoritative answer for your machine.
- Set a shortcut you can hit blind This matters more than it sounds. A shortcut you have to look for will not survive a busy day. Something under your left hand, not used by anything else.
- Click into a text field and press it Notes or a Mail reply. A microphone indicator appears. Speak.
- Stop by pressing the shortcut again Dictation also stops on its own after about thirty seconds of silence.
The four habits that decide whether this works
Almost everyone who abandons dictation does so for the same reasons, and none of them is accuracy. They are habits, and all four are learnable in a week.
1. Speak a whole thought, then stop
The instinct is to dictate one word, check it, dictate another. That is slower than typing and feels terrible. Speak an entire sentence or a short paragraph, release, and only then look at the screen. Speech models use the surrounding words to decide what a word was, so a complete thought is genuinely more accurate than the same words dictated piecemeal.
2. Read it back. Every time.
Ten seconds of reading is part of the workflow, not evidence that it failed. Dictating three sentences takes eight seconds and reading them takes ten. Typing them takes forty-five. The arithmetic still works, and the read-back is what stops an embarrassing sentence reaching a client.
3. Say the punctuation, at least at first
"Full stop", "comma", "question mark", "new paragraph". It feels ridiculous for about a day and then becomes invisible. Modern models will place punctuation for you, but they guess, and your guess is better. Once you trust the app's placement you can stop — some people do, some never do.
4. Teach it the words it keeps getting wrong
This is the one that separates people who dictate daily from people who tried it once. A general speech model has never heard of your client, your colleague or your product. Built-in dictation cannot be taught; apps with a custom vocabulary can. Keep a note for a week of every word you correct — it will be a list of about fifteen proper nouns, not a general accuracy problem.
Week one, untaught
Ask see ob han to send the deck to N.H.S. digital before wednesdays stand up and check if key ran has the P.O.
Week two, after teaching fifteen words
Ask Siobhán to send the deck to NHS Digital before Wednesday's stand-up, and check if Kiéran has the PO.
Where to dictate, and where not to
A system-wide dictation tool types wherever your cursor is, so it works the same way in every app. It does not integrate with Slack or Mail or Word; it does not need to. That is why the list below has no exceptions in it.
- Email. The highest-return use by a distance. Most replies are three sentences you already know how to say. See dictating email.
- Chat. Slack, Teams, Messages. Short messages, spoken faster than typed. See dictating in Slack.
- AI prompts. Prompts are the ideal dictation task: long, rambling and disposable. See dictating better prompts.
- First drafts. Anything where the point is to get words down and fix them later.
- Notes to yourself. Nobody else reads them, so the bar is low and the speed gain is total.
Where dictation is a poor fit: anything with heavy formatting, spreadsheets, code (though prompts about code are fine), passwords, and anywhere you would not be comfortable speaking aloud. An open-plan office is a real constraint and no software fixes it.
The three things that go wrong in week one
| What you see | What it usually is | Fix |
|---|---|---|
| Nothing happens when you press the shortcut | Another app owns the same key, or accessibility permission was never granted | Change the shortcut; check System Settings → Privacy & Security → Accessibility |
| Text appears in the wrong place | The cursor was not in the field you thought | Click into the field first, every time. It becomes automatic |
| Names and jargon are consistently wrong | The model has never heard those words | Use an app with custom vocabulary and teach it fifteen words |
| Text arrives garbled or out of order | Dictating over the top of an app that is still processing | Wait for the previous dictation to land before starting the next |
| It is accurate but feels slow | You are dictating word by word | Speak whole thoughts, read back once |
When to pay for a dictation app
There are four honest reasons, and if none applies, keep using the free one:
- You correct the same proper nouns every single day and built-in dictation cannot learn them.
- You dictate confidential material and need the audio to stay on your machine as a matter of architecture rather than policy.
- You want a history of what you dictated, with the audio, so you can recover something that went wrong.
- You want short spoken triggers that expand into whole blocks of text — a sign-off, an address, a standard paragraph.
If one or more of those is true, the shortlist of Mac dictation apps covers the options, including the ones we do not sell.
Questions
Do I need to buy anything to dictate on a Mac?
No. Dictation is built into macOS, it is free, and on Apple silicon it can run on your Mac. Paid apps add custom vocabulary, snippets, a replayable history and control over how the text is tidied. Start with the free one for a week.
How long can I dictate for in one go?
Apple states you can dictate text of any length without a timeout, and that dictation stops after about thirty seconds of silence. In practice, shorter bursts of one paragraph each are easier to read back and easier to correct than one long monologue.
Does dictation work in every app?
System-wide dictation — including macOS's own and apps like VV — types wherever your cursor is, so yes, in any app with a text field. Browser-based dictation pages and in-app features such as Word's dictate button only work inside their own window.
Will people hear me dictating?
Yes, and this is the most under-discussed limitation of dictation. It works badly in open-plan offices, on trains and in shared houses. There is no software answer. Most people who dictate daily do it at a desk with a door, or wear a headset and speak quietly — a good close microphone lets you speak much more softly than you would expect.
Is dictation actually faster than typing?
Speaking is roughly twice as fast as most people type, but the fair comparison includes the read-back and the corrections. For email, chat, notes and first drafts it is comfortably faster. For anything heavily formatted, it is not. See can you speak faster than you type.
