Speech coding using motion picture compression techniques

Motion picture compression standards are well developed and widely used in multimedia applications. It could be very convenient to have only one coding algorithm implemented on a multimedia device which deals with video as well as audio and speech data. In this paper, we present a new approach to speech coding where we apply motion picture compression techniques to speech signals. An audio-to-video converter is proposed which prepares the speech or audio data to allow direct processing by a video coding algorithm (e.g. MPEG) and a video-to-audio converter which reconstructs the speech signal.
