These are my configuration parameters for coding wave files of training, adaptation and test data. All of them are 16 Khz and 16 bit , mono
SOURCEFORMAT = WAV
TARGETKIND = MFCC_0_D_A
SAVECOMPRESSED = T
SAVEWITHCRC = T
WINDOWSIZE = 250000.0
TARGETRATE = 100000.0
NUMCEPS = 12
USEHAMMING = T
PREEMCOEF = 0.97
NUMCHANS = 26
CEPLIFTER = 22
ENORMALISE = F
Is it ok?

Hi Rauf,
the choce of TARGETKIND can have a pretty big impact on resulting accuracy, see this post (you can find my configs in the package I posted yesterday).
Unfortunatelly my results do not agree with what is reported in the literature, see this. I guess further investigation is needed.
Regarding your offer to post your training scripts, I have some ideas, but first I need to finish a couple of other things. I will write about it later.

I have started a new thread to discuss what should be done about these training scripts.

Hi all,
Finally I found out the reason of poor results with adapted models. As I said, when using adapted models with HDecode, it showed warnings "no token survived to the sent end"
I was performing adaptation steps in HTK Book. I changed the HADAPT:SPLITTHRESH parameter in config.rc file, from 1000 to 5000, and it started working.
Results of HDecode with speaker-independent models was 65% and it increased to 73% with adapted models.
Thank you for your help, also thank you Tomas for your adaptaptation script
