Abstract:
Methods and systems employing an internal microphone and an external microphone of a headset to capture own voice content in the presence of noise, extract the own voice content from background noise (by performing noise reduction on the microphone outputs to generate a noise reduced signal indicative of the own voice content), and optionally also perform voice activity detection to identify segments of own voice presence or absence. In some embodiments, the external microphone is employed to capture the own voice content, the internal microphone signal is employed to infer the noise captured by the external microphone, and the inferred noise is subtracted from the external microphone signal to generate the noise reduced signal. Aspects include methods performed by any embodiment of the system, and a system or device configured (e.g., programmed) to perform any embodiment of the method.

Claim (Index 6):
The method of  claim 1 , wherein step (b) includes performing residual noise reduction on the equalized noise reduced signal.
