I made a.arpa with CMUSLM2.0,and context cues with <s></s>

Why <s></s> are predicted  in my "a.arpa" file ,If there are not <s></s> in my a.text then the result will be "b.arpa",and if b.vocab without <s></s> then will be the "c.arpa" and what i should do ?

This is my file:

a.text

<s>  NEW E-MAIL  </s>

<s>  BACKWARD </s>
<s>  NEXT WINDOW </s>
<s>  LAST WINDOW </s>
<s>  OPEN MUSIC PLAYER </s>

Both your models are not correct, just because you are using too old and broken software. I suggest you to try lmtool:

  http://www.speech.cs.cmu.edu/tools/lmtool.html

 You can just upload your text there and get proper model and a dictionary.

I used cmucmslmtk V3,which is a new version,and I need use this tool to get my LM.

Do you think this tool is broken ?

It's not the latest version, the latest one is in trunk or in form of nightly build on cmusphinx sourceforge site

> Do you think this tool is broken ?

The tool itself is not broken, you are using it incorrectly just because ngrams in your result have unknowns and silences. Compare them with the proper result from online lmtool.

It's possible to get the same with offline cmuclmtk but since you don't provide details on what you are doing, it's hard to help you.

Sorry ,I just want to use this tool to get LM and I find what I got is not the same as online lmtool!

This is what I have done: 

I prepared a.text:

OPEN BROWSER
NEW EMAIL
FORWARD
BACKWARD
NEXT WINDOW
LAST WINDOW
OPEN MUSIC PLAYER

and a.ccs:<s>

2.and I got a.sent.text with cmd `sed`.a.sent.text:

<s>  OPEN BROWSER </s>
<s>  NEW EMAIL </s>
<s>  FORWARD </s>
<s>  BACKWARD </s>
<s>  NEXT WINDOW </s>
<s>  LAST WINDOW </s>
<s>  OPEN MUSIC PLAYER </s>

3.Got a.wfreq and a.vocab  with the cmd text2wfreq and wfreq2vocab.

a.vocab:

 ## Vocab generated by v2 of the CMU-Cambridge Statistcal
## Language Modeling toolkit.
##
## Includes 13 words ##
</s>
<s>
BACKWARD
BROWSER
EMAIL
FORWARD

4.Got a.idngram with text2idngram

5.Got a.arpa with cmd idngram2lm

Excuse me for being too irritated. Mostly it's ok. A few things to correct the lm:

1. Online Lmtool uses QuickLM from here, it counts 3-grams differently:

  http://www.speech.cs.cmu.edu/tools/download/quick_lm.pl

you can also use it. Alternatively, you can just filter wngrams (don't get idngrams directly, get wngrams first and then strip them with grep:

 ./text2wngram < input.txt | grep -v "</s> <s>"  > input.wngram

 the rest will work as usual:

 ./wngram2idngram -vocab input.vocab < input.wngram > input.idngram

 ./idngram2lm -vocab_type 0 -idngram input.idngram -vocab input.vocab -arpa input.arpa

Please note that you need latest trunk to make it work more or less properly.

2. Don't generate open vocabulary model, sphinx ignores unknowns, so pass   -vocab_type 0 to idngram2lm

Thank you!

And I got a.wngram as you said:

<s> NEW EMAIL 1
<s> NEXT WINDOW 1
<s> OPEN BROWSER 1
<s> OPEN MUSIC 1
LAST WINDOW </s> 1
MUSIC PLAYER </s> 1
NEW EMAIL </s> 1
NEXT WINDOW </s> 1
OPEN BROWSER </s> 1
OPEN MUSIC PLAYER 1

When I got a.idngram(-write_ascii), I think  what I got was something wrong!

 40000000 40000000 40000000 1141473616

Why?

Yes, there was a bug that I fixed just yesterday, please try to checkout cmuclmtk from trunk and rebuild it.
