Why Mac dictation keeps stopping
It is not a bug and you are not doing it wrong. Apple's Dictation ends itself when you stop talking, and there is no setting that changes it.
The short answer
Dictation stops after roughly 30 seconds without speech. Pausing to think, checking a reference, or taking a long breath reads to the system as "finished".
There is no preference to extend that window. The related toggle changes when a pause ends the session, not how long the session may last.
What is actually happening
The limit is not on how long you may dictate. On Apple Silicon and recent macOS you can dictate at length. The limit is on silence: stop speaking for around thirty seconds and Dictation decides you are done and switches itself off.
That is why it feels arbitrary. It fires exactly when you pause to think, which is the moment you least want to be interrupted, and never when you are talking continuously.
On an Intel Mac there is a second problem underneath it: Dictation there processes audio on Apple's servers, so it needs a connection and behaves worse without a good one.
The workarounds, honestly
- System Settings ▸ Keyboard ▸ Dictation ▸ Auto-Ends Dictation When You Stop Speaking. Turning it off stops a pause from ending the session, which helps. It does not remove the underlying stop.
- Keep pauses short. Real advice, and a miserable way to write — it means composing out loud without thinking.
- Restart it each time. What most people end up doing, and the reason dictation gets abandoned.
There is no setting that extends the window, because Apple does not expose one.
The thing that removes it
A push-to-talk model has no timeout to hit, because the session is not guessing when you are finished — you are telling it. Hold a key while you speak, release when you are done. Pause for a minute mid-sentence and nothing happens, because nothing is listening for the end.
That is how Voz works. Hold your hotkey, talk, release, and the text appears wherever your cursor is. Transcription runs on your Mac with a Whisper model inside the app, so it also works with no connection at all — which matters on an Intel Mac, where Apple's Dictation is the one that needs the network.
To be fair to Apple's Dictation
It is free, already installed, and on Apple Silicon it runs on-device and handles ordinary sentences well. If the thirty-second stop is not something you hit, there is no reason to replace it, and we would rather say that than sell you something you do not need.
Voz is $2.99 once. It is worth it if you dictate long enough to be interrupted by a limit you cannot change.
