I think the important line here is "head sil word "<s>" not exist in voca"

Check to see that you have the lines

<s>    sil
</s>    sil

someplace in the file pointed to by the -v parameter. If not, insert them and try again. I don't think the positioning is important, see discussion in https://github.com/julius-speech/julius/issues/15 - I have found some variability in the output of language model generators that can lead to some confusion when loaded by Julius.

Thanks it worked. But now I'm getting this:

------

### read analyzed parameter

enter MFCC filename->

I pluged in macros file:

------

### read analyzed parameter

enter MFCC filename->macros

and I'm getting this error:

input MFCC file: macros

Warning: rdparam: header says it has 2121206332 frames (more than 10 minutes)

Warning: rdparam: it may be a little endian MFCC

Enter MFCC filename-> is the kind of prompt I get when I forget to state that I'm intending to use the mike as input and Julius starts making assumptions. Are you sure that macros belongs here?

Hi John,

I have just gone to follow the training recipe you linked to but can't seem to find a way to download the LDC's Gigaword text corpus. Is there a secret to this I don't know about?

LDC's Gigaword text corpus

I tried that link earlier. I couldn't see a download link on the page so I created an account, logged in and now just get a nice big error message when trying to load that page again that says:

We're sorry, but something went wrong.

The LDC controls copyright on the corpus. You cannot get to it unless you buy a membership and DVD or become a student and get permission that way. In any case you are probably taking too big a bite at the problem; you don't need the entire corpus if you are content to try the already existing LMs (see the downloads on the link you already have) that have been generated by others.

To find out how to use a LM, create a simple LM from a Librivox book text with one of the freely available LM generators, or even better convert a grammar that you know works to a LM by scripting a "corpus" based on the grammar, run an LM generator over it, and then set Julius to work on the resulting LM with the audio model you have from the grammar. Once you have some experience, go back to the LMs derived from the LDC corpus if necessary.

But first, find out what a LM looks like, generate a few and toss them away just so you know what they consist of.

Thanks (once again!) for the advice. You are really helping me get an understanding of something I knew nothing about!

I downloaded a 2gram and 3gram bundle from the link above. I plugged the 2 arpa files into mkbingram using the following command:

mkbingram -nlr lm_giga_64k_vp_2gram.arpa -nlr lm_giga_64k_vp_3gram.arpa outfile.bingram

I then setup my test.jconf file to be:

## Language model file(s)

-d lm/outfile.bingram

## Word dictionary file

-v tutorial/sample.dict

## Acoustic HMM file

-h tutorial/hmm15/hmmdefs

-hlist tutorial/tiedlist

I run julius with this test.jconf but get:
