HTK HEREST ISSUE

I'm doing some speech recognition using HTK (HMM ToolKit) and I'm getting this odd error:

ERROR [+7390] StepAlpha: Alpha prune failed sq(16) > qHi(15)

I have tried to play around with pruning but only those 15/16 would change to other numbers, I keel receiving the same error. I've even tried to disable pruning and it keeps giving me this error.

I just don't know where to look for anything, if I knew I could fix it.

this is my HERest command:

HERest -C config -I Label.mlf -t 250 100 1000 -S trainlist.scp -H hmms\0\vFloors -H hmms\0\hmm0 -M hmms\1 wordlist

I've looked into the HTK book but there is nothing about the error number 7390.

In my case it was related to big (15 MB) file in input data. It worked after deleting it. Run HERest with -T 1 option to see which file causes problem, then remove or split it.

You must adjust -t parameter. This error occur when pruning is failed, so with modify prune parameter. I have this problem and with -t 10 it's solved!

I work with the HTK toolkit off and on, but not with HEREST. I also have never seen the error that you have encountered. A quick search on the web reveals some links that may be helpful.

  1. Link 1

Scroll to the bottom of the link above, and you see an error code like ??9?. This means that a sanity check has failed. It further says that the error has nothing to do with your code, but that the HTK itself may be faulty. I think, given that Error 7390 has not occurred any where else, and that it also fits your error code, you might want to consider re-installing HTK.

  1. Link 2
    The link above shows a lot of common errors and its causes seen when working with the HTK toolkit. The original poster has painstakingly put up errors and common conditions that cause them. Saved me a lot of effort. In my eyes, she deserves the Nobel (or something like that).

  2. Link 3
    This link gives more detailed, module by module error codes. Also worth a look.

Do let me know here how you were able to solve your problem.
HTH,
Sriram.
