Abstract
Double-talk detection systems and methods are provided that include a plurality of microphones and array processing to detect when a vehicle occupant is speaking. One or more array processors combine the microphone signals to provide a primary signal and a reference signal. The responses of the primary signal and the reference signal are different in the direction of an occupant location. A comparison of energy content is made between the primary signal and reference signal to selectively indicate double-talk based on the comparison.
