Design of a Applied System Based on TMS320C5402 DSP
【摘要】 介绍一种基于TMS32 0C5 40 2DSP芯片的压缩语音录放系统的软硬件设计方法 .该系统通过对语音进行压缩以实现高效率数字录音 ,可应用于电话留言、语声应答等场合 .其中电话留言是本系统的一个典型应用
【Abstract】 It is proposed that a design technique can record and paly voice and is based on TMS320C5402 DSP including hardware and software. The system, by means of compressing voice and storing data,can be used in leaving word of phone and voice responsion and so on.Leaving word of phone is a typical application.
