Hi All,
if i set my cepstral coeffcients to be 12. Then i did log energy,
delta coefficients and double delta coefficients.

Does that mean i'm suppose to get 39 coeffcients as my result??

12 cepstral coeff
12 delta cepstral coeff
12 double delta cepstral coeff
1 energy coeff
1delta energy coeff
1 double delta energy coeff
---------
39

Yes you are correct
One coefficient for log energy + 12 for cepstral
coefficients = 13 coeffs
Then obtain delta of the above = 13 additional coeffs
and delta-delta = 13 coeffs
hence, total = 39 coeffs
