Speech to text on a Mac turns your spoken words into typed text, and there are two kinds worth knowing: the built-in feature included with macOS, which types what you say word for word, and AI speech to text, which transcribes and then cleans the result into finished, correctly-punctuated text. The built-in option is free and fine for quick verbatim notes; AI speech to text is what you want when the words need to be ready to send.
The two kinds of speech to text on a Mac
Every Mac already has speech to text built in, and it works everywhere your cursor does — but it transcribes verbatim, so filler words, false starts and missing punctuation all land in the text exactly as you said them. AI speech to text does the same transcription step and then rewrites the raw words into clean sentences with punctuation, capitalization and paragraphs added for you. The practical difference is what you do next: verbatim transcription usually needs editing before you can use it, while AI speech to text aims to hand you text that's already finished.
How to use the built-in speech to text
1. Turn it on — open System Settings → Keyboard → Dictation and switch it on. 2. Choose your language — under Languages, add or pick the one you'll speak; the first use may download a model, and on Apple Silicon it can then run on-device and offline. 3. Set the trigger — the Shortcut menu decides what starts dictation (commonly pressing the Fn/🌐 Globe key twice). 4. Speak into any text field — put your cursor where the text should go, fire the shortcut and talk. Remember you'll need to speak punctuation out loud (“comma”, “period”, “new line”), because the built-in feature won't add it for you.
What actually drives accuracy
Speech-to-text accuracy is mostly about the input, not magic: a decent microphone placed close to you, a quiet room without echo, and a steady, clear speaking pace do more than any setting. The right language has to be selected, and any specialised words — names, brands, product and technical terms — are where every engine struggles most, because they're not in ordinary speech. A modern AI transcription model handles accents and natural speech better than older on-device recognition, and pairing it with a custom dictionary of your own terms is what finally stops the same names from being mangled every time.
When AI speech to text is the better pick
If the transcript is the finished product — an email, a message, a document, a prompt to an AI tool — AI speech to text saves the editing pass that verbatim transcription forces on you. It punctuates and paragraphs automatically, cleans up the “ums” and restarts, and can match the register to where the text is going, so a quick chat stays casual and an email reads professionally. For rough personal notes you'll retype anyway, the free built-in feature is perfectly adequate; for anything you'll send to another person, finished text is worth more than raw words.
AI speech to text that's ready to send
Clavio is AI speech to text for Mac: it transcribes what you say and rewrites it into polished, correctly-punctuated text in the tone you pick, then pastes it straight into whatever app is in front — mail, chat, browser, editor. A personal dictionary keeps your names and jargon spelled right. It's free to try — 3,000 polished words a month, no card, macOS 14+ on Apple Silicon.

Common questions
Does the Mac have built-in speech to text?
Yes — every Mac includes speech to text through the built-in Dictation feature, turned on at System Settings → Keyboard → Dictation. It types your words verbatim into any text field and, on Apple Silicon, can run on-device once the language model has downloaded.
What's the most accurate speech to text on a Mac?
Accuracy depends more on your microphone, a quiet room and clear speech than on the app, but a modern AI transcription model generally handles accents, natural speech and long sentences better than older on-device recognition. Adding your own names and jargon to a custom dictionary is what removes the last recurring errors.
Is speech to text on Mac free?
Yes — the built-in Dictation feature is free and included with macOS. AI speech-to-text apps typically offer a free tier with a monthly word cap and charge for unlimited use; Clavio's free tier includes 3,000 polished words a month with no card.
What's the difference between speech to text and AI dictation?
Plain speech to text transcribes your words verbatim, leaving punctuation and cleanup to you, while AI dictation transcribes and then rewrites the result into finished, correctly-toned text. The transcription step is the same; AI dictation adds the editing you'd otherwise do by hand.
