ABSTRACT:
A system for performing recognition having a telephone transmitter, a camera, a data channel and recognition processing logic, in which the camera is directly mounted to and positioned with respect to the telephone housing to obtain video information from a non-direct frontal view of the speaker corresponding to at least one facial feature for use in speechreading. The facial features that may be obtained include the position of the tongue, separation of the teeth and the rounding protrusion of the lips. Using this data, recognition processing logic performs speechreading recognition of the video information.
