You press the dictation key, start talking, and somewhere in the second or third sentence it quietly gives up. The little microphone disappears. Whatever you said after that is gone, and you did not notice for another twenty words.

This is the single most common complaint about dictating on a Mac, and it is not one bug. It is four or five different behaviours that all look identical from where you are sitting. Here they are, roughly in the order you should check them.

1. It stopped because you paused

Apple's keyboard dictation ends the session after a short silence. Not a long one — a beat or two while you think of the next word is enough on some setups.

This is the cause most of the time, and it is the one people misdiagnose most often, because pausing to think does not feel like doing anything. You are not "idle". You are composing the sentence. The microphone disagrees.

There is no setting for it. You cannot lengthen the silence window in System Settings, and no combination of language and model changes it meaningfully. What people do instead is talk through the pauses — filling the gaps with "um" so the session stays alive — which works, and is a miserable way to write.

2. It hit a hard time limit

On some configurations dictation stops after a fixed stretch whether you pause or not, in the region of thirty to forty seconds. This is a server-side limit, and it applies when your dictation is going to Apple's servers rather than running on the Mac itself.

Whether yours runs on-device depends on your Mac and your language. Apple silicon Macs on a recent macOS run many languages entirely on-device; Intel Macs, and less-supported languages, generally do not. The tell is simple: turn off Wi-Fi and try to dictate. If it still works, you are on-device and this is not your problem. If it refuses, everything you say is making a round trip, and the time limit is real.

If you are on-device and dictation still cuts out, go back to cause 1. Local dictation removes the hard limit; it does not remove the silence timeout.

3. Something else grabbed the microphone

Only one thing gets the input device at a time in the way dictation wants it. A video call in the background, a recording app you forgot was open, an audio interface that dropped and reconnected — any of these can end a dictation session instantly and without a message.

Check System Settings → Sound → Input while it is happening. If the input device is not the one you think it is, or the level meter is dead while you talk, the problem is upstream of dictation entirely and no amount of fiddling with language settings will fix it.

Bluetooth headsets deserve their own mention. When a Bluetooth headset switches into its microphone mode, the audio quality drops to something close to a telephone call, and dictation accuracy falls off a cliff at the same moment. If your transcription got suddenly, dramatically worse rather than stopping, this is usually why.

4. The language download is missing or half-finished

Dictation languages download separately. If the download failed, or was interrupted, or the disk was full at the wrong moment, dictation can appear to be enabled and configured and still fail the moment you use it.

In System Settings → Keyboard → Dictation, remove your language and add it back. Give it a few minutes on a real connection. It is a boring fix and it resolves a surprising number of cases that look like something much more exotic.

5. Voice Control is not the same feature

Two different things on the same Mac are both called dictation in casual conversation.

Keyboard dictation is the microphone key. It types what you say and it stops on its own, which is this whole page.

Voice Control lives in System Settings → Accessibility → Voice Control. It is a full hands-free control layer — it clicks things, it navigates, it has a proper command grammar, and it stays on until you tell it to stop. It was built for people who cannot use a keyboard at all, and it is genuinely capable.

It is also, for most people, too much. Voice Control is always listening, it interprets everything you say as a possible command, and turning it on changes how your entire Mac behaves. If you searched for why dictation keeps stopping and someone told you to enable Voice Control, that advice is not wrong, exactly. It is just an enormous answer to a small question.

What to try, in order

• Dictate with Wi-Fi off. If it works, you are on-device; if it does not, you are on the server path and the time limit applies to you.
• Watch the input meter in Sound settings while it fails. A dead meter is a microphone problem, not a dictation problem.
• Remove and re-add your dictation language.
• Quit anything else that touches the microphone, then try again.
• If it only stops when you stop talking, nothing here will fix it. That one is by design.

Why this keeps happening

Every one of these behaviours is reasonable on its own. A session that ends on silence saves battery and stops your Mac transcribing the room. A time limit on a server call is ordinary engineering. Handing the microphone to whatever asked most recently is the right default nine times out of ten.

They add up badly, though, because none of them tell you what happened. Dictation does not say "I stopped because you went quiet" or "I stopped because I have been listening for forty seconds". It just stops, and you find out later, from the gap in the paragraph.

What Mynato does differently

We built Mynato because of cause 1, honestly. Thinking mid-sentence should not end the sentence.

• You decide when it stops. Hold the key while you talk and let go when you are done, or use a continuous session that stays open through every pause you take, however long.
• No time limit, because there is no server. The speech model runs on your Mac. Nothing goes anywhere, so nothing can time out, and it works in a tunnel with the Wi-Fi off.
• It types where your cursor already is — any app, no window to switch to, nothing to paste.

It is a paid app with a free tier that does not expire, it needs an Apple silicon Mac and macOS 13 or later, and you can read exactly what costs money before you install anything.

If you only came for the fix, though, take the Wi-Fi test and the language re-add and go back to your document. That is what the page is for.
