GSC-based spatial voice activity detection for enhanced speech coding in the presence of competing speech.

GSC-based spatial voice activity detection for enhanced speech coding in the presence of competing speech.

An array of microphones is used for both noise suppression and spatial voice activity detection (SVAD). A generalized sidelobe canceler (GSC) is employed for robust adaptive interference rejection and the signals within the GSC are also exploited to provide speech activity detection for the desired...
