Abstract
A sound system of a vehicle includes a plurality of microphones disposed in a cabin of the vehicle, a plurality of speakers disposed in the cabin of the vehicle, and a sound processor operable to process microphone output signals of the microphones to determine a voice signal of a speaking occupant in the vehicle at or near one of the microphones. The sound processor generates a processor output signal that is provided to at least some of the speakers. Responsive to the processor output signal, the at least some of the speakers generate sound representative of the voice signal of the speaking occupant to direct the sound towards other occupants in the vehicle, while one or more speakers at or near the seat occupied by the speaking occupant do not generate sound representative of the voice signal of the speaking occupant.
