先用端点检测将语音中有用的语音部分提取出来（即将头部和尾部的静音部分除掉），然后用LPC算法提取语音信号的特征参数，进行动态归整(DTW算法)后与模板库里面的标准语音作比较，最后将识别结果进行D/A转化后播放出来。在本部分的设计中，则主要完成语音识别的模式匹配算法部分的软件实现。 -First with the endpoint detection of speech to voice some of the useful extracted from the (soon to mute some of the head and tail removed), and then extract the speech signal with the LPC algorithm characteristic parameters of dynamic warping (DTW algorithm) after the template library compared to standard voice inside, and finally the recognition result is D/A conversion after playing out. In this part of the design, mainly to complete the pattern matching algorithm for speech recognition part of the software.
