Welcome to Android Central! Can the other person hear you well if you're on speakerphone, or a wired or Bluetooth headset? If so, then the primary phone mic (at the bottom of the phone) is either blocked or faulty. Inspect the mic opening closely to see if it's clogged by debris, or if it's blocked by a case.
