Welcome to Android Central! Can people also hear you when you use a wired or Bluetooth headset? If so, then the primary mic is either blocked or faulty. Check the mic opening and see if it's clogged by debris, or if it's blocked by something like an ill-fitting case. If everything is clear and it still doesn't work, then the mic itself might have to be replaced.
