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?
>No tokens survived to final node of network at beam 550.0
This means that HVite could not recognize the sentence with the words: "tktb mdrsaat aalkaatbaan ktb". Did you create your own pronunciation dictionary?
YOu might have to fiddle with the HVite -t parameter to increase your beam width (see this post)
Note that you need to create "Questions" for your language in order to create triphone acoustic models in Step 9 and 10.
>ERROR [+6510] LOpen: Unable to open label file train/mfcc/sample24.lab
Likely a path issue - HTK is very finicky in this respect...
