If the microphones on your iPhone, iPad, and iPod touch aren't working
If the sound is unclear during phone calls or FaceTime calls, or if Siri is unable to detect your voice, learn what to do.
With your iOS device, you might experience one of these issues when you make a call, use FaceTime or Siri, or play recorded audio:
Test the microphones on your device
To find out if there’s an issue with the microphone on your device—and not your cellular connection or the app that you're using—test each microphone. Microphone location can vary by device. You can use your product's technical specifications to find the microphones.
When you test your microphones, make sure that your iOS device isn't connected to a wired or wireless headset.
iPhone
There is more than one microphone on your iPhone.

To test the primary microphone on the bottom of your iPhone, open Voice Memos and tap the record icon. Then speak into the microphone and tap the play icon to play back the recording. You should be able to hear your voice clearly.
To test the front microphone, open the Camera app and record a video using the front camera. To test the rear microphone, open the Camera app and record a video using the back camera. When you play back the video you should hear your voice clearly.
If your voice sounds faint when you’re on a phone call, make sure that your rear microphone isn’t blocked or covered.
If Siri can't hear you, make sure that the receiver and front microphone on top of your iPhone aren't covered or dirty.
iPad
To test the microphone on your iPad, make sure that nothing is covering the microphone, and then open Voice Memos and tap the record icon. Speak into the microphone, and then tap the play icon to play back the recording. You should be able to hear your voice clearly. Learn where the microphones are located on your iPad.
iPod touch
To test the microphone on your iPod touch, open Voice Memos. Tap the record icon, speak into the microphone, then tap the play icon to play back the recording. You should be able to hear your voice clearly.
