bug in scripts/Training.pl or HTKTools/HMGenS.c?

Question

I am trying to build a voice file using Tensorflow, with the HTS demo voice HTS-demo_CMU-ARCTIC-SLT. But it crashes with segfaults. After checking for null on a few pointers in HHed.c and Model.c to prevent segfaults, I ran Again and got segfaults in HMGenS.

On investigation , I found that the hmmDir and hmmExt are initialized to NULL, but were being referenced anyway.

I tried to provide a value for hmmDir in scripts/Training.pl but it still crashes because hmmExt is NULL.

What is the correct way to build a voice using Tensorflow to generate a Voice File for HTS-demo_CMU-ARCTIC-SLT?

suggests that the configuration file you created is wrong. It used question file instead of scp file which should just list the filenames. You need to review the configuration and try to figure out how question file placed there. Most likely you just confused the files on preparation.

You've also asked this question on mailing list.
