Hi ken,

In fact the problem of UBM is very simple. We have just to model all speakers with one set of GMM (one state of HMM). So my question is : I have one wav file and I'd like to train it. First, I had extract MFCC features then I used HCompV to initialize my model then I'm trying to obtain my HMM model by HERest as :

HERest -C config/config_train_mfcc -I label/label_EE4H_noSP.mlf -t 250.0 150.0 1000.0 -S list/listTrainFulPath.scp -H hmmsTrained/hmm0/macros -H hmmsTrained/hmm0/models -M hmmsTrained/hmm1 lib/wordList_noSP

where "listTrainFulPath.scp" contain "C:\htk-3.3\bd/train_f_1_1.mfcc"

my problem is what should I write in "label_EE4H_noSP.mlf" and "lib/wordList_noSP".

Can you help me in this case. Thanks
