Abstract

Abstract Automatic synchronization of movement of a computer generated mouth to movement of a real mouth uttering words. Establishing signals to define the basic form of the mouth generated by the computer for display on a display tube. Combining high frequency sine and cosine signals with the basic form signals to form the body of the mouth on the display tube with modulation of the high frequency signals for shaping the lips. Utilizing pattern recognition and filtering signals of different frequencies that correspond to different spoken sounds. Combining the filtered signals to create control voltages representative of the realistic or alternatively, intentionally impressionistic motions of the mouth corresponding to the spoken sound. Using the control voltages to control movement of the beam of the display tube to effect the amplitude of movement of the upper lip, the amplitude of movement of the lower lip, and the width of the mouth generated by the computer. Controlling the intensity of the beam as the mouth is drawn and animated.
