Abstract
A method, apparatus, and manufacture for speech enhancement in an automotive environment is provided. Signals from first and second microphones of a two-microphone array are decomposed into subbands. At least one signal processing method is performed on the each subband of the decomposed signals to provide a first signal processing output signal and a second signal processing output signal. Subsequently, an acoustic events detection determination is made as to whether the driver, the front passenger, or neither is speaking. An acoustic events detection output signal is provided by selecting the first or second signal processing output signal and by either attenuating the selected signal or not, based on a currently selected operating mode and based on the result of the acoustic events detection determination. Each subband of the acoustics events detection output signal is then combined.
