说明：  介绍了基于TMS320C5509DSP芯片的语音分析系统的工作原理，给出了整体设计方案和工作框图，然后给出了系统的硬件设计方案； 接着介绍了基于TMS320C5509DSP芯片的语音录放系统的软件设计。 该语音录放器的设计能够完成语音采集，存储，滤波，频谱分析，基本实现了语音分析功能。
(Speech analysis system works based on TMS320C5509DSP chip, given the overall design and block diagram of the hardware design of the system then introduced based on TMS320C5509DSP chip voice recording system software design. The voice recording is designed to complete speech acquisition, storage, filtering, spectrum analysis, basic voice functions.)
