本文结合梅尔滤波器组和翻转梅尔滤波器组的优势，提出了一种混合滤波器组。-this paper combines the advantages of Mel filter banks and Inverted Mel filter banks, and proposes a hybrid filter banks.

MFCC已经广泛地应用在语音识别领域。由于Mel频率与Hz频率之间非线性的对应关系，使得MFCC随着频率的提高，其计算精度随之下降。因此，在应用中常常只使用低频MFCC，而丢弃中高频MFCC。这个程序是求MFCC 的-MFCC has been widely used in speech recognition. Mel frequency Hz as a nonlinear correspondence relationship between the frequency, such as t
