Abstract
A method for adjusting an operational characteristic of an audio device can include a series of steps. The method can include receiving a user spoken utterance from an audio speech source and detecting a position of the audio speech source relative to the audio device. The method further can include generating proximity data corresponding to the detected position and processing the received user spoken utterance with a selected signal processing technique based upon the proximity data. The signal processing technique can distinguish the user spoken utterance from background noise.
