    语音识别中的两种特征提取方法lpcc和mfcc,还有一个是文本无关的识别算法dtw,另外还有一个是预处理消噪部分的。共享一下,这些都是我调试过的,好用。(Speech Recognition two feature extraction methods and mfcc lpcc. There is a text-independent recognition algorithm dtw, in addition to a pretreatment is part of the noise source. Sharing that those are off the debugging and ease of use.)
