基于DSP的语音识别系统及其结构

A Speech Recognition System and Structure Based on the DSP

介绍了一种基于TM S320C 54xxDSP的语音识别系统及语音端点检测的过程,以及隐尔马柯夫模型(HMM)运用到语音识别的基本原理。最后介绍了TM S320C 54xxDSP芯片的一些特点,同时也展现了语音识别技术在今后日常生活中的前景和用途。

This paper present a speech recognition system based on the TMS320C54xx DSP. Firstly we introduce the theory and process of the speech state bit test. Secondly we present how to use the Hidden Markov Model （HMM） method into whole system. Finally the characteristic of TMS320C54xx DSP is summarized in this paper. The outlook and use of the speech recognition technology in our people＇s life is also fixed eyes on by us.
