hi everybody

when i run step 8

http://www.voxforge.org/home/dev/acousticmodels/linux/create/htkjulius/tutorial/monophones/step-8

and when i checked and reviewed the hvite_log file (the log output) i saw that  HVite did not recognize all the words for each line in your prompts file.

like with:

Aligning File: train\mfcc\sample24.mfc

Created lattice with 6 nodes / 5 arcs from label file

No tokens survived to final node of network at beam 250.0

No tokens survived to final node of network at beam 400.0

No tokens survived to final node of network at beam 550.0

SENT-END tktb mdrsaat aalkaatbaan ktb SENT-END == [261 frames] -58.3549 [Ac=-15230.6 LM=0.0] (Act=21.5)

that make my step wrong after that

 ERROR [+6510]  LOpen: Unable to open label file train/mfcc/sample24.lab
FATAL ERROR - Terminating program HERest

how i can solve that? and why this file doesnot recognise these words?

You have to change sample24.

The file sample24 has too many long world.

Also you can add manually the information of aligned.mlf, editing aligned.mlf, than you can go on with tutorial.

If Herest investigates more fault label, you have to edit aligned.mlf adding other missing label ;-)

Have a nice day C.
