摘　　要：本次系统实现了基于AMBE2000的低速率语音通信,该芯片采用改进的多带激励(MBE)算法,能实现可变速率低比特率、高语音音质的语音压缩编码。本文通过实例,给出了以AMBE2000为核心,语音压缩传输以及解压输出的电路实现。本实验获得了低速率下良好的语音质量,为越来越重要的低速率高质量语音通信提供了有利参考,具有很高实用价值。This system realized a voice communication system based on the AMBE2000, this chip uses the MBE algorithm to obtain low changeable communication rate, and higb speech quality. The design shows the eireuit of the system in detail, and results of superior voice quality at low data rates. As the low rate high quality is more and more important in the voice communication system, this experiment is very valuable.
