When dictation won't start on a Mac, work through six things in order: turn Dictation on, verify the shortcut, free the function keys, grant microphone access, let the on-device model finish downloading, and restart. Nine times out of ten it's the shortcut, the microphone input, or a stuck speech service — not a broken Mac.
The six-step checklist
1. Turn Dictation on — System Settings → Keyboard → Dictation, switch it on and click Enable; if it was already on, toggle it off and back on to re-register the shortcut. 2. Check the shortcut — the Shortcut menu shows what triggers dictation (often pressing the Fn/🌐 key twice); if it does nothing, pick a different trigger. 3. Free the function keys — if a single F-key launches dictation, turn on Keyboard Shortcuts → Function Keys → 'Use F1, F2, etc. as standard function keys'. 4. Grant microphone access — the app needs mic permission and the right input device selected in System Settings → Sound → Input; a muted or wrong input is the most common 'it types nothing' cause. 5. Download the on-device model — first use may need a one-time language download; until it finishes, dictation can silently do nothing, so leave it a few minutes on Wi-Fi. 6. Restart and re-test — a stuck speech-recognition process is cleared by a logout or reboot more reliably than by toggling settings.
If the shortcut is the problem
The most common single failure is the trigger key. Apple's built-in Dictation is fired from System Settings → Keyboard → Dictation → Shortcut, and if another app claimed that key, or the function-key setting is swallowing it, pressing it does nothing. Reassign it to a trigger you don't press by accident, toggle Dictation off and on to re-register, then test in a plain text field like Notes before blaming a specific app.
If it types nothing at all
A dictation shortcut that lights up but produces no text is an input problem, not a recognition one. Check that the correct microphone is selected in System Settings → Sound → Input, that the level meter moves when you speak, and that the frontmost app has microphone permission. On first use, a one-time on-device language download must complete before any words appear — that silent wait fools a lot of people into thinking dictation is dead.
When you want it to just work
If you spend more time coaxing the built-in feature than dictating, a dedicated app removes most of these failure points: it manages its own microphone capture and its own shortcut, and it turns the transcript into finished, correctly-toned text instead of raw words. Clavio for Mac is free to try — 3,000 polished words a month, no card, macOS 14+ on Apple Silicon.

Common questions
Why is my Mac dictation shortcut not working?
Usually the shortcut got reassigned, the function-key behaviour is intercepting it, or the speech service is stuck. Open System Settings → Keyboard → Dictation, confirm the Shortcut is set to a trigger you're actually pressing, then toggle Dictation off and on to re-register it. A logout or reboot clears a stuck service.
Dictation is on but types nothing — what's wrong?
It's almost always microphone input: the wrong input device is selected, the app lacks mic permission, or the on-device language model is still downloading. Check System Settings → Sound → Input and the app's microphone permission, and give a first-time model download a few minutes.
Why does dictation keep stopping after a few seconds?
That's a separate limit, not a fault — Apple's built-in Dictation ends after about 30 seconds of continuous speech and on short pauses. See our note on the 30-second cap for the workaround and how to dictate longer.
Is there a more reliable way to dictate on a Mac?
A dedicated dictation app manages its own microphone capture and shortcut, so it sidesteps the built-in feature's quirks. Clavio also cleans up the transcript into finished text and works in any app.
