摘　　要：语音处理系统广泛地应用于许多场合,满足了人们对多媒体业务的需求。文章设计了一种语音处理系统,该系统采用TMS320VC5502作为主处理器,选用TLV320AIC23B作为Codec芯片,在此基础上完成系统的硬件平台搭建和软件编程。该系统充分利用DSP处理器的特点,提高了语音处理的速度,具有一定的实用性。Voice processing system is widely used in multimedia services. This paper designs a voice processing system. This system adopts TMS320VC5502 as the main processor and TLV320AIC23B as Codec chip, and the system＇s hardware platform and software flow are realized based on them. By making full use of DSP, the system gets a higher voice processing speed.
