How-to Acoustic Model Creation Script - HVite error: Unable to open label file

[kmaclean]

​sjmacgregor said: I am running the accoustic model creation script on Linux and I get the following error in step 8:

realign hmm7

"ERROR [+6510] LOpen: Unable to open label file interim_files/mfcc/sample1.lab

FATAL ERROR - Terminating program HVite"

I am using HTK 3.3.

What am I doing wrong?

Workaround:

Each line of your prompts file likely needs a "*/" (star & forward slash) before each file name. Your first prompt line should look something like this:

*/sample1 DIAL ONE TWO THREE FOUR FIVE SIX SEVEN EIGHT NINE OH ZERO

I looks like the prompts file in Step 2 of the How-to was updated to exclude the "*/", but the acoustic model training script was not updated.

Action: need to update acoustic model creation script (in how-to and tutorial) to fix this ...

Need to create a VoxForge version of HTK's prompts2mlf script or update prompts file in How-to to include "*/".

Subroutine from VoxForge HTK_Compile_Model.sh script:

make_wordsmlf () {
	perl ../../HTK_scripts/prompts2mlf ./interim_files/words.mlf ../prompts
	return 0
}
