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

thanks!

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
