Mac Dictation Not Working: How to Fix It
Nine causes in the order they are worth checking, including the three that produce a microphone that looks alive and records nothing at all.
“Dictation is not working” covers two very different faults. Either nothing starts at all, or it starts, shows you a live microphone, and types nothing. The second is far more common and almost never a dictation problem — it is an audio input problem. Work through these in order.
1. Check microphone permission
Open System Settings › Privacy & Security › Microphone and confirm the app you are dictating into is switched on. macOS grants a recording app permission to run and then hands it silence when permission is missing, so nothing looks broken. If you have just toggled the switch, quit and reopen the app — the permission is read at launch.
2. Check which microphone is actually selected
System Settings › Sound › Input. Speak, and watch the input level meter. If the bars do not move, the problem is upstream of dictation and no amount of restarting will help. Pick a different device and test again. A Mac that has recently been on a call often has a virtual or conferencing device selected rather than a real one.
3. Closed lid, dead microphone
The built-in microphone array lives in the display. Run a MacBook in clamshell mode with an external monitor and that array can stop delivering audio while macOS keeps listing it as an available input. Recording starts normally, the level meter sits flat, and no error is raised anywhere. This one does not fix itself over time: either open the lid or select a different input device.
4. AirPods and Bluetooth headsets stuck in output mode
Bluetooth headsets negotiate a profile when they connect. Land in an output-only profile and the headset stays in the input list while delivering nothing. Disconnect and reconnect them from Control Centre, or choose a wired or built-in microphone instead. Bluetooth also takes a few seconds to negotiate, so give it a moment before deciding it is broken.
5. It broke right after you changed hardware
Docking, undocking, plugging in a USB microphone or switching to headphones changes the sample rate the input device runs at. An app that negotiated the previous rate can carry on with no error and no audio — the recording indicator is lit, the timer counts up, the transcript is empty. If dictation stopped working within a minute of plugging something in, quit the app that is listening and reopen it. That resets the negotiation.
6. Another app has the microphone in a strange state
Meeting and screen-recording apps apply system-level voice processing to the input device, and that setting is shared by every app on the Mac. The symptom is distinctive: your voice is suddenly very quiet everywhere, not just in one app. Quit the meeting app fully — menu bar included — and test again. If the whole Mac's microphone is still wrong afterwards, a restart clears it.
7. The language pack has not downloaded
In System Settings › Keyboard › Dictation › Languages, a language that is still downloading will not transcribe, and on a slow connection this takes longer than people expect. Remove the language and add it again if it appears stuck.
8. Something else owns your shortcut
If pressing the shortcut does nothing at all, another app or a system function has claimed it first. The Globe (fn) key is the usual culprit: macOS assigns it to the emoji picker or to switching input sources on many keyboards, and it never reaches dictation. Check System Settings › Keyboard, look at what “Press Globe key to” is set to, and either set it to Do Nothing or pick a different dictation shortcut.
9. A managed Mac
If the Dictation toggle is greyed out and will not respond, the Mac is probably enrolled with a school or employer that disables it by policy. Nothing local will change it; your IT team has to.
Still nothing?
Turn Dictation off in System Settings › Keyboard, restart the Mac, then turn it back on and re-add your languages. A restart also clears a wedged audio daemon, which is what is left when the input level meter refuses to move for any device.
Dictation that tells you when the mic is dead
Most of the faults above are silent by design: macOS reports a healthy device and hands over an empty signal. Ahsk watches whether audio is actually arriving, switches to a working microphone mid-sentence when one stops delivering, and says so instead of returning an empty transcript.
