[hts-users:04314] about zero-th mel cepstral coefficient

[Tuan Dinh <tuan.dinh@xxxxxxxxx>]

Dear all,

The mcep is used in hts to extract mcc. 

The results are in the format:

c1(1), c1(2), ........, c1(M), ... , cf(1), cf(2), ... , cf(M) 

with M is the order of mcc (M=49 in hts)  and f is the number of frames.

What is zero-th mel cepstral coefficient? (Is it c1(1) or c1(M))?

Thanks for spending your time on my email.

Best regards,

-Tuan
