Hi , I'm trying to use HTK in Window 7. When I complie the .grammar and .voca files with mkdfa.jl file, I have error below:

"sample.grammar has 3 rules
---
sample.voca has 6 categories and 24 words
generated: sample.term
---
Now parsing grammar file
"rror:       Lexical mistake "
ERROR: LoadError: failed process: Process(`mkfa.exe -e1 -fg 'C:\Users\user\AppData\Local\Temp\jul1EB6.tmp/g3384.grammar' -fv 'C:\Users\sev_user\AppData\Local\Temp\jul1EB6.tmp/g3384.voca' -fo sample.dfa.tmp -fh 'C:\Users\user\AppData

I don't know how to fix it. Can U help me?

Thank you!

The error output is suggesting that there is an error (possibly a typo) in the .grammar file. One way to debug is to go back to a very basic and simple grammar/voca setup (such as provided in the Voxforge tutorials) and verify that mkdfa works in that case. Then gradually adapt and retest the known working setup to your own custom grammar until the error pops. Then you know where the error is.

Make sure in composing your grammar and voca files that you use a very simple plain ASCII editor to ensure that you don't use any weird characters which might cause mkdfa to choke.
