Welcome to Android Central! Which phone? Can they hear you on speakerphone, or using a wired or Bluetooth headset? If so, then there's a problem with the primary phone mic at the bottom of the phone. Make sure the opening isn't clogged by debris, or blocked by a case. If it's clear, then the mic itself may have failed.
