ERROR [+7332] CreateInsts: Cannot have successive Tee models
FATAL ERROR - Terminating program HERest
This is the error I got in the penultimate step. i.e, when I run the following 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
See if Ken's comments in http://www.voxforge.org/home/dev/acousticmodels/linux/create/htkjulius/tutorial/monophones/step-7/comments/errore-creating-file-for-hmm6 are relevant to your situation. If not, please comment on what is different in your case.
