Abstract:
A signal processing device for configurable voice activity detection. A plurality of inputs receive respective microphone signals. A microphone signal router configurably routes the microphone signals. At least one voice activity detection module receives a pair of microphone signals from the router, and produces a respective output indicating whether speech or noise has been detected by the voice activity detection module in the respective pair of microphone signals. A voice activity decision module receives the output of the voice activity detection module(s) and determines whether voice activity exists in the microphone signals. A spatial noise reduction module receives microphone signals from the microphone signal router, and performs adaptive beamforming based in part upon the output of the voice activity decision module, and outputs a spatial noise reduced output. The device permits simple configurability to deliver spatial noise reduction for one of a wide variety of headset form factors.

Claim (Index 1):
A signal processing device for configurable voice activity detection, the device comprising:\n a plurality of inputs for receiving respective microphone signals; a microphone signal router for routing microphone signals from the inputs; at least one voice activity detection module configured to receive a pair of microphone signals from the microphone signal router, and configured to produce a respective output indicating whether speech or noise has been detected by the voice activity detection module in the respective pair of microphone signals; a voice activity decision module for receiving the output of the at least one voice activity detection module and for determining from the output of the at least one voice activity detection module whether voice activity exists in the microphone signals, and for producing an output indicating whether voice activity exists in the microphone signals; a spatial noise reduction module for receiving microphone signals from the microphone signal router, and for performing adaptive beamforming based in part upon the output of the voice activity decision module, and for outputting a spatial noise reduced output.
