Compression Ang Transmission Of Low Speed Voice Based On DSP System

Along with the development of Voice's Digital Signal Process technic, Developers' research interests are attracted by research and practice application of low speed voice's encoder and decoder. The paper is completed in this background, it takes several months do it. The paper syncretize DSP (Digital signal processor) and CPLD (complex programmable logic device) technic. The paper expatiates design of the practice apply system using the AMBE arithmetic, and introduces the correlation field and applied range about Voice's Digital Signal Process .and talks about the superiority of low speed voice's vocoder. The important parts are the applied hardware design and software about it. The manuscript drawings , software glow chart about speech input/output and channel interface are offerd. These part questions faced and settle methods about debugging are expatiated too...
