sounds like a bad mic. The iPhone 5 has 3 mics, one at the bottom, one by the camera, and one in the earpiece ( the metal mesh on the front above the display). You can isolate which one is bad by recording a voice memo (uses the mic at the bottom), make a call and use the speakerphone (uses the front mic) and record a video (uses the back mic) I suspect that the bottom one wont work. you can try restoring the phone, but it's most likely a hardware issue and needs to be serviced.
