A voice acquisition system for a vehicle includes an optical sensor disposed at an interior portion of the vehicle and having a sensing field that encompasses a driver's head region in the vehicle cabin typically occupied by a driver's head. An optical sensor processor is provided for processing an output of the optical sensor to determine optically-derived vocal signals emanating from the driver. A microphone is provided and is operable to receive audible signals from in the vehicle cabin. A microphone processor is provided for processing an output of the microphone to determine audio-derived vocal signals emanating from the driver. A control, responsive to processing of the output of the optical sensor by the optical sensor processor and processing of the output of the microphone by the microphone processor, isolates the driver's voice from other acoustic noise.
