librosa.feature.melspectrogram is not equal as kaldi's mfcc extraction

Open KnowBetterHelps opened this issue 6 years ago • 2 comments

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
