Abstract:
An audio device with at least one microphone adapted to receive sound from a sound field and create an output, and a processing system that is responsive to the output of the microphone. The processing system is configured to use a signal processing algorithm to detect speech in the output, detect a predefined trigger event indicating a possible change in the sound field, and modify the signal processing algorithm upon the detection of the predefined trigger event.

Claim (Index 20):
An audio device, comprising:\n a plurality of microphones that are configurable into a microphone array and are adapted to receive sound from a sound field and create an output; and a processing system that is responsive to the output of the microphones and is configured to:\n use a normally off adaptive beamformer signal processing algorithm to detect speech in the output of the microphones, wherein the beamformer is configured to use multiple microphone outputs to detect speech in the output, and wherein the beamformer comprises a plurality of beamformer coefficients; \n detect a predefined trigger event indicating a possible change in the sound field, wherein the predefined trigger event comprises one or more of an increase in noise in the sound field, the passing of a predetermined amount of time, and an input from a sensor device; and \n in response to the detection of the predefined trigger event, turn on the adaptive beamformer, calculate new beamformer coefficients, store the new beamformer coefficients for use in detecting speech, and turn off the beamformer algorithm.
