librosa.feature.melspectrogram is not equal as kaldi's mfcc extraction
the same audio, when I use librosa.feature.melspectrogram to extracte log mfcc, says Matrix A(43,N). But it turns out that Matrix A is not equal as kaldi's mfcc extraction, says Matrix B(43,M), even their dims, N != M. Got very confused, Could any help me?
The method of dividing frames in librosa and Kaldi is different, and you can refer this issue: https://github.com/librosa/librosa/issues/595
Is it because melspectrogram equal to fbank?not mfcc?
