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

-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
