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 you 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 may 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, device microphone malfunctions may be caused by problems with the telephone line . 

Other times the iPhone has a component mounting defect on the electronic board that manages the audio. To do so, it would have to be repaired

Sometimes it happens that the voice messages are ‘empty’ to the recipient 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 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.
