Use Hardware → Microphone in Device Status⁺ for a quick input-response check. Start with the phone’s built-in microphone route rather than a connected headset.
Run a voice input check
- Disconnect wired audio accessories and Bluetooth headsets.
- Open Hardware → Microphone and allow microphone access.
- Start the microphone test using the page’s recording control.
- Stay quiet briefly and observe the input level.
- Speak at a normal volume from an ordinary conversation distance.
- Compare the level while speaking with the quiet baseline, then stop the test.
Keep the microphone openings clear. Do not insert tools or liquids into them.
Read the signal
A level that responds to speech confirms that audio is reaching the app through the active input. It does not prove that every microphone in the phone works, because iOS selects inputs according to the audio session and route.
A high level also does not guarantee clear audio. If your complaint is muffled or distorted speech, make and replay a recording in Voice Memos or Camera as a separate listening check.
If there is no response
Check microphone permission, stop any competing recording or call, and repeat with accessories disconnected. Remove a case that might cover an opening. Record which app and route fail if the problem persists.
To investigate playback separately, follow the volume test.
