Microprocessor based speech encoding technique

Abstract

This paper presents a possible application of the contractivity speech coding techniques. There exist systems developed for recording, storing, and transmitting audio data over a network which like other computer applications, use the client/server model to implement data manipulation, In addition, to enhance productivity, graphic interfaces could improve their usability by adding sound as another channel for conveying information, but due to wideband constrains in the transmission channel, all these new audio protocols require techniques for coding/decoding audio signal in order to achieve compression rates capable of reducing the bandwidth to levels acceptable by the channels. The authors present an overview of a new encoding methodology, linear contractivity speech coding (LCSC), that, when applied to a speech signal, provides one with very high compression rates.
