An apparatus (10) and method (30) for automatically controlling the sound level of human speech in an output audio signal (26) generated from an input audio signal (16). A gain controller (12) only increases the gain of an amplifier (14) used to produce the output audio signal (26) from the input audio signal (16) when a detector (30) signals that the input audio signal (16) includes human speech.
