摘　　要：在一个基于TMS32 0C5 4 10和 5 4 16的双DSP局域话音通信系统的设计中 ,为保证话音与数据通信的可靠性与实时性 ,由 5 4 16负责话音的采集与处理 ,实现了包括语音检测、语音编解码、回声消除、自适应降噪等语音处理算法。完全满足系统的设计要求。In one local speech communication system design based on double DSP combined by TMS320C5410 and 5416, to assure the reliability and the real time performance of the speech and data communication, we arrange 5416 to collect and process the speech data, and realize a series of speech algorithms including speech detector, speech coder and decoder, echo canceller, adaptive noise canceller on 5416. All of the programs completely meet the expectations of system design.
