Design of a speech processing system based on dsp 的语音处理系统设计
A new speech processing system 一种新型语音处理系统
It is essential for speech processing system to have robust speech detection . a pca ( principal component analysis ) - based speech detection was proposed . we get a very good result form the examination of using this method 本文提出了将pca应用于语音检测,实现了语音和非语音的正确检测,并通过实验证明了这种方法是可行的,而且检测效果比较好。
Secondly , the design of the wideband speech processing system based on dsp is described . finally , the haredware and software of the system is expatiated , which includes the design of system architecture and its intefaces ; the programming and debugging of software in dsp , the driver of the speech gathering card and the interrupt service of tms320vc5416 接着讲述了基于dsp的宽带语音处理系统的总体设计,包括系统架构设计、算法与芯片选型等。然后是宽带语音处理系统的硬件组成与接口设计。最后是宽带语音处理系统的软件实现,包括dsp的数据接收与发送的实现, dsp主程序与采集卡驱动程序的设计、编程与调试, dsp中断处理的实现等。
