Using various signal processing technologies, a microphone system has been developed to enhance hands-free communications in automobiles. The steered microphone array functions as a highly directive beamforming spatial filter, thereby emphasizing the location of the selected talker. Experimental results demonstrate that a steered response power-phase transform algorithm is robust in reverberant and noisy environments.
