Hii all,

I am trying to make a decoder for myself. I need the feature parameters from htk.

I have used the same wav_config file as given in the tutorial for my HTK recognition software.But when i try to see the feature parameters(.mfc file) using the command HList , it shows 26 vectors per frame instead of 25(mfcc(12) + delta (12) + 0th(1),which it should show).

sample1.mfc

         6.462   7.283  68.259  -0.076  -0.009   0.427   0.709  -1.433  -1.166   0.350
        -0.488  -2.145  -0.693  -0.609   0.688   0.029

Am i wrong here conceptually?

If not then which vectors to take while calculating the observation probabilites for continuos densities(because we have used a proto having 25 vectors in the next step).

Plz help me understand htk..

thnx
