Hi,
i did not see you reply to me. Thanks.
i've also found from scikits package a pure python implementation of mfcc.

I have 2 questions:
- the mfc file is a binary file. Is it possible to view the matrix in clear? Is there a document about the structure of file. I would like to use the mfcc matrix in a python program?
- do you know a DTW program which can compare 2 mfcc file?

regards,
Laurent

sphinx_cepview converts it to text

Is there a document about the structure of file.

4-bytes header contains integer - number of floats in a file. Then floats go
one by one each in 4 bytes.

I would like to use the mfcc matrix in a python program?

I'm not sure what stops you here.
