It may happen that during a phone call , a FaceTime call , recording an audio message , using Siri the microphone does not work.

The result can be as follows: The other party cannot hear you during a normal or FaceTime call;
Siri does not hear the request or does not understand it at all;
When playing audio, no or bad sound is heard;
Cannot record audio messages ;
You cannot change the audio source during a call or the loudspeaker does not work.

Test the operation of the microphones

Make sure that the problem is with the microphone itself and not with the applications you are using.

The microphones (bottom, front, rear) can be tested in the following ways:

• lower the microphone : opens the Voice Notes and record a message, if when you listen to the recording again you feel bad or are not heard at all, the microphone is not working;
• Front microphone : open the Camera and record a video with the front camera (the front one) saying something, if you don't hear your voice or you hear it wrong, you might have a problem with the microphone in question or you use the Siri voice assistant asking for example the time or the weather, if it answers you correctly then the microphone is working;
• Rear microphone : open the camera and record a video with the camera on the back (rear) speaking again. If you hear your voice clearly when you listen to the video again, the microphone is working, otherwise there is obviously a problem.

Sometimes malfunctioning microphones in devices may be caused by problems with the telephone line . 

Other times the iPhone has a assembly defect of a component on the electronic board that manages the audio. It would have to be repaired

Sometimes it happens that the voice messages are 'empty' for the addressee This may be due to the iPhone's lack of memory from which they are sent. It is advisable to check if the device has run out of storage space and free it up if necessary.

Probably also, the phone may simply be full of dust and we will have to remove it manually, or take it for repair if it has a much more serious problem.
