Abstract
MFCC is very successful in speech recognition
* MFCC computed from the speech signal using
the following three steps:
1.Compute the FFT power spectrum of the speech signal
2.Apply a Mel-space filter-bank to the power spectrum to get N
energies (N=20~60)
3.Compute discrete cosine x’form (DCT) of log filter-bank energies
to get uncorrelated MFCC’s (M=10)
