摘要： Embodiments relate to apparatuses for, and methods of, compensating for distance 206 and velocity present between a microphone and user's 202 mouth. Such devices and methods allow compensation for varying amplitudes of sound pressure received at a the due to a varying distance 206 between a microphone and an originating user's 202 mouth. Additionally, the devices and methods may also compensate for pitch shifts due to a Doppler effect caused by a non-zero velocity of a microphone relative to a user's 202 mouth.
