Hi RedCisc,

>Error [+7321] CreateInsts: Unknown label sil

HTK book says:

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

Looks like you did not create a 'sil' model in your hmmdef file... your monophones0 file should contain a sil phone.

Ken

Yes. That was it. The monophones0 file was missing the sil as its last command.

 at step Fixing silence 

the error for following command

 HERest -A -D -T 1 -C input_files/config -I interim_files/phones1.mlf -t 250.0 150.0 3000.0 -S train.scp -H interim_files/hmm5/macros -H interim_files/hmm5/hmmdefs -M interim_files/hmm6 interim_files/monophones1

Thank you a lot. Your reply solved my problem

How can I solve the following eror

ERROR [+7321]  CreateInsts: Unknown label .

 FATAL ERROR - Terminating program C:\htk\bin.win32\HERest

>ERROR [+7321]  CreateInsts: Unknown label .

it looks like it is telling you that you have a '.' (a period) as a label in your words.mlf...

I am guessing that you might have two consecutive lines with periods in them in your words.mlf file.
