All,

I am newbie and following Voxforge STEP#6 link - http://www.voxforge.org/home/dev/acousticmodels/linux/create/htkjulius/tutorial/monophones/step-6 for creating FLAT START MONOPHONES.

I tried below command but getting errors as -

$ HERest -A -D -T 1 -C config -I phones0.mlf -t 250.0 150.0 1000.0 -S train.scp -H hmm0/macros -H hmm0/hmmdefs -M hmm1 monophones0
HERest -A -D -T 1 -C config -I phones0.mlf -t 250.0 150.0 1000.0 -S train.scp -H hmm0/macros -H hmm0/hmmdefs -M hmm1 monophones0

But, if I HACK as -

P { margin-bottom: 0.21cm; }A:link { }

“cp ../../manual/phones0.mlf .” to /train/mfcc folder, rename as .lab file. Delete first two lines, last '.' line and remove 'sil' from .lab file. Huuuuh..  it works as -

It tries to look into phones0.mlf for label for X1.lab and doesn't find it. You need to look into phones0.mlf file yourself and check what labels are there and why label for X1.lab is missing. If it's really missing you need to return to previous step when phones0.mlf was created.

If you don't know the reasons you have an option to share your files, that will enable us to suggest you more detailed solution.
