Patent US 4,177,589

An artificially animated face with three-dimensional facial features formed of a flexible material is provided with remotely actuable concealed mechanisms for manipulating the jaw, rounding the mouth, and drawing the lower lip inward relative to the upper lip. The face is operated by an audio input either from a microphone or from an audio tape. The audio input is fed both through an audio amplification system to a speaker located proximate to the face, and also to an audio encoder which senses the major frequencies of the spoken sounds of the audio input and produces one or more digital signals in response thereto. If an "F" sound is detected, the lower lip of the figure is drawn inward to a slight degree, thus simulating human lip movement in sounding the consonant "F". If the decoder detects an "O" sound, the mouth is rounded in response thereto. If the decoder detects an "A" sound, the mouth is drawn into a line. The eyes of the figure may be blinked upon receipt of a specified number of digital signals, and a wind jet may be operated in tandem with the mechanism for drawing the lower lip inward to simulate the expulsion of air from the mouth in conjunction with an "F" sound.
