METHOD AND SYSTEM FOR VOICE CAPTURE USING FACE DETECTION IN NOISY ENVIRONMENTS

Embodiments of the present invention are capable of determining a face direction associated with a detected subject (or multiple detected subjects) of interest within a 3D space using face detection procedures, while simultaneously avoiding the pick up of other environmental sounds. In addition, if more than one face is detected, embodiments of the present invention can automatically detect an active speaker based on the recognition of facial movements consistent with the performance of providing audio (e.g., tracking mouth movements) by those subjects whose faces were detected. Once determinations are made regarding face direction of the detected subject, embodiments of the present invention may dynamically adjust the audio acquisition capabilities of the audio capture device (e.g., microphone devices) relative to the location of the detected subject using beamforming techniques for instance. As such, embodiments of the present invention can detect the direction of the "talking object" and guide the audio subsystem to filter out any sound not coming from that direction.
