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?
Apple says current macOS Dictation has no time limit while you keep speaking. It stops automatically after about 30 seconds with no speech. If it stops while you are actively talking, check the microphone signal, selected input, language, and connection instead.
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.
