Mac dictation microphone not working: how to fix it

Published 18 October 2026

If dictation starts but doesn't seem to hear you, the microphone is the first suspect. Most of the time the microphone works fine and the Mac is simply listening to a different one, or the app isn't allowed to use it. These checks go from the quickest to the more involved.

Check which microphone Dictation uses

Dictation has its own microphone setting, separate from the rest of the system. Open Apple menu → System Settings → Keyboard and scroll to Dictation. Next to Microphone source you'll see either a device name or Automatic. Apple says that on Automatic, the Mac listens to the device you're most likely to use for Dictation. With a monitor, a webcam and a headset all plugged in, "most likely" often means the wrong one. Pick the microphone you're actually talking into.

Check the input in Sound settings

Next, open System Settings → Sound and click Input. Select the same microphone in the list of input devices. Then look at the input volume slider. Apple suggests raising it for people who speak softly. If the Mac isn't responding to your voice at all, Apple's troubleshooting page says to select the microphone here and increase its input volume.

If your Mac has no built-in microphone, Apple says an external one has to be connected and selected in Sound or Keyboard settings. Dictation can't use what isn't there.

Bluetooth headsets and external displays

A Bluetooth headset or AirPods appear in the same Input list once they're connected. Select the headset there and as the Dictation Microphone source if you want to dictate through it.

Displays with their own microphone cause a specific problem. Apple notes that when a headset is plugged into a Mac connected to a display, choosing the display's microphone can switch back to the headset. The fix is to unplug the headset first, then choose the display's microphone. If you'd rather use the headset, select it in both places and leave the display microphone alone.

Check app permissions

Apple's own Dictation is part of macOS, but third-party apps and browsers have to be allowed to use the microphone. Go to System Settings → Privacy & Security → Microphone. Apple describes this as a list where you turn microphone access on or off for each app. If your dictation app, browser or Word is switched off, nothing it records will contain your voice.

Some apps also complain when another program is holding the microphone. Microsoft's advice for the "We don't have access to your microphone" message in Office is to close other apps that might be using it and try again. The same idea helps elsewhere: don't run two dictation tools at once.

Check the room and how you speak

Apple's checklist includes some plain physical points. Make sure nothing, such as clothing or your hand, covers the microphone. Sit as you normally would and speak clearly at a moderate volume. In a noisy or echoing room, a headset microphone may help, because it sits close to your mouth.

Test it

Open Control Center while you talk. Apple's Recording Indicator shows when the microphone is in use or has been used recently, which at least tells you whether something is listening. Then open TextEdit, choose Edit → Start Dictation and read a sentence aloud. If text appears now, your microphone works. If dictation hears you but still drops the text in one particular app, the general dictation checklist covers shortcuts, languages and app problems.

Testing with a dictation app

A dictation app that keeps your recordings gives you one more test: listen back. Saypad saves every dictation with its audio in the history window. If the playback is silent, muffled or full of room noise, you know the problem is the microphone or its settings, not the recognition. If nobody was heard at all, Saypad says "No speech heard" instead of pasting something made up.

Saypad asks for exactly two permissions, Microphone and Accessibility, and the setup window puts a checkmark next to each one once it's granted. If a permission doesn't register within 10 seconds, setup tells you what to do. Speech is recognized on your Mac, so you can test without a connection. For how it compares with Apple's engine on the same sentence, see Saypad vs Apple Dictation.

Questions

Why does my Mac pick the wrong microphone for dictation?

Dictation's Microphone source can be set to Automatic, which listens to the device your Mac thinks you're most likely to use. With a display, webcam or headset connected, that guess can be wrong. Pick the microphone yourself.

Can I use AirPods or another Bluetooth headset for dictation?

Yes, once it's connected you can select it as the input in System Settings → Sound → Input, and as the Microphone source under Dictation. If the Mac keeps switching back, choose the device again in both places.

How do I know if any app can hear me?

Apple's Recording Indicator in Control Center shows when the microphone is in use or has been used recently. It also lights up when you open the Input section of Sound settings.

Does a dictation app need its own microphone permission?

Yes. Third-party apps need to be switched on in System Settings → Privacy & Security → Microphone. Apps such as Saypad also need Accessibility to type into other apps.
