  This paper presented several familiar feature extracting methods such as Linear Prediction Cepstrum Coefficient (LPCC) and Mel Frequency Cepstrum Coefficient (MFCC). They have got excellent recognition results under clean environment, but their performance will deteriorate severely in noisy condition.

  文中首先介绍了几种常用的特征提取方法如线性预测倒谱系数(LPCC)和Mel频率倒谱系数(MFCC),这两种特征在静音环境下有很好的识别效果,但在噪音环境下,性能就会严重下降。
