Hello there, I have been using the quickstart linux nightly package for a few days and have ran into problems trying to use the HTK_AcousticModel nightly. From what I can see, the nightly Julius quickstart package contains the hmmdefs and tiedlist from the HTK_AcousticModel already. But julius is still using the sample.dict and sample.dfa of just 23 words. I would like to use the larger 11,000 word dictionary from the HTK_AcousticModel package but I’ve struggled to find any information on preparing Julius-friendly dict & dfa files.

Can you point me in the right direction?

Kind Regards,

Oko

Hi Oko,

Yes, they are the same

See step 1 of the acoustic model creation tutorial. 

Note:If you are using the dict file included with the nightly build, you need to remove the "sp" phone from the pronunciations for each word you use for the Julian grammar.  Ticket #294 provides some details.  

Since the Nightly build uses tied-state triphone acoustic models, you can use the VoxForge pronunciation dictionary too:

Hope that helps,
