基于TMS320C5509DSP的语音处理系统平台硬件设计

摘要

语音信号的处理的关键技术是数字信号处理，文章结合数字信号处理技术，进行了语音处理系统的研究，并设计了一种基于DSP的语音处理系统。该系统主要以TI公司的DSP芯片TMS320C5509作为处理核心，以数字形式对信号进行采集、变换、滤波等处理，得到了符合需要的通用语音信号处理的硬件平台。%The digital signal processing (DSP) is the key technology of the speech signal processing. This paper studies the speech processing system with the digital signal processing technology, and designs a speech processing system based on DSP. The system uses TMS320C5509 (a DSP chip of the TI Company) as the processing core to collect, convert and filter the signals in digital form, and finally builds a hardware platform according to the required versatile speech signal processing.
