I have a problem during the re-estimation for 11 times after the triphones compilation has been succeded.

the command :

HERest -A -D -T 1 -C config -I wintri.mlf -t 250.0 150.0 3000.0 -S train.scp -H hmm10/macros -H hmm10/hmmdefs -M hmm11 triphones1

and it gives me this error :

ERROR [+7321] CreateInsts : Unknown label B

I'll already followed and checked everything, but can't find the solution...please help me!

 Thank you;

Hi Annie,

The HTK book states the following with respect to your error:

+7321 Unknown model
      Model in HMM List not found in HMMSet, check that the correct HMM List is being used.

It seems like your triphone1 file (which contains your list of triphone hmms) contains a label "B" that does not exist in your hmm file.  Try removing it and running HERest again to see what happens.

Have you changed your aligned.mlf file (which creates your triphone1 file) from what was created in Step 8? 

Hope that helps,
