摘　　要：介绍了一种利用TI公司的CODEC、TLV320AIC23和DSP芯片TMS320VC5509,实现的语音信号的采集及播放系统。具体阐述了二者之间的接口设计和如何通过TMS320VC5509的I2C模块,对TLV320AIC23进行初始化以及通过TMSVC5509的McBSP实现两者之间的正常数据通信。A speech acquisition and playing system based on TMS320VC5509 and TLV320AIC23 of TI Company is introduced. The design of the interface between the two chips is discussed in detail. How to initialize the TLV320AIC23 through the I^2C module of TMS320VC5509 and how to implement the normal data transfers between the two chips through MeBSP are also discussed.
