MFCC，Mel频率倒谱系数的缩写。Mel频率是基于人耳听觉特性提出来的，它与Hz频率成非线性对应关系。Mel频率倒谱系数(MFCC)则是利用它们之间的这种关系，计算得到的Hz频谱特征，MFCC已经广泛地应用在语音识别领域。-MFCC, Mel Frequency Cepstral Coefficients abbreviations. Mel frequency is proposed based on the human auditory characteristics. It comes with a nonlinear correspondence Hz frequency. Mel Frequency Cepstral Coefficients (MFCC) is the use of such a relationship between them, calculate Hz spectral characteristics obtained, MFCC has been widely used in speech recognition.
