Welcome to Android Central! Check the phone mic opening to make sure it isn't blocked or clogged with debris. If it looks fine, then the mic might have failed.

I had to stick an earring end in the mic to unclog it worked like a charm. Of u do tht at your own risk worked for me thoe

This exact thing happened to my S5 a few months ago. After talking on speaker for weeks I finally brought my phone in. Got a replacement. Worked fine for a few weeks then same thing. Got another replacement. Within two days the third replacement had same issue. It must be an app or SIM card or??? Anyone have any ideas? Verizon is clueless at this point.

If you keep it in the same linty place, it could be clogging the hole in days every time.

Can't be the SIM card - that would prevent the call if it was defective, not outgoing audio.

It could be an app holding onto the internal mic, but since we don't know what apps you have installed, the guesses would be all over the map.
