Abstract
A wind noise reduction system includes a delay and sum (DAS) beamformer, an MVDR beamformer, a wind detector, a GEV beamformer, and a fixed voice mixer. The DAS beamformer generates a first voice signal based on a first and second microphone signal. The MVDR beamformer generates a second voice signal based on the first and second microphone signals. The GEV beamformer generates a wind array voice signal based on the first and second microphone signals and an accelerometer signal. The wind detector generates a wind detection signal based on the first voice signal and the second voice signal. The fixed voice mixer generates an output voice signal based on a microphone array voice signal, the wind array voice signal, and the wind detector signal. If high winds are detected, the output voice signal includes elements of the wind array voice signal based in part on the accelerometer signal.
