problem in creating .dmp file from .lm file

[Basit Mahmood]

Hi to all,
Hope you all will be fine. Actually i am new to sphinx 4. The problem is i
have created a text file and then created the language model using lmtool.
Then i downloaded the utility lm3g2dmp and then tried to convert my .lm file
to .dmp format. But when i try to do this. I got an error. I am doing this on
linux. I want to ask a question
Is it necessary to convert my .lm file to .dmp format? Can i use .lm file
directly without converting it to .dmp?
How can i convert my .lm file to .dmp on windows xp?

lm3g2dmp is obsolete tool, you shouldn't use it. To find information about
conversion see our tutorial:

http://cmusphinx.sourceforge.net/wiki/tutoriallm#converting_model_into_dmp_fo
rmat

When you ask about error always try to describe it in details, provide error
message, provide a command you are running, describe your expectatations

Is it necessary to convert my .lm file to .dmp format?

Yes

Can i use .lm file directly without converting it to .dmp?

No

How can i convert my .lm file to .dmp on windows xp?

Using sphinx_lm_convert from sphinxbase.

Hi thanks:)
It has been converted. Actually i was using the wrong syntax. I want to ask a
question. Suppose i use JSGF grammer file, then what parameters i will use in
xml file for dictinary, filler and .lm.DMP files. Because in this case there
is only one file (.gram file).

<component name="trigramModel" type="edu.cmu.sphinx.linguist.language.ngram.large.LargeTrigramModel">
    <property name="unigramWeight" value="0.7"/>
    <property name="maxDepth" value="3"/>
    <property name="logMath" value="logMath"/>
    <property name="dictionary" value="dictionary"/>
    <property name="location" 
    value="the name of the language model file 
           for example <your_training_folder>/etc/<your_model_name>.lm.DMP"/>  ..in case of JSGF what it will be?
  </component>

  <component name="dictionary" type="edu.cmu.sphinx.linguist.dictionary.FastDictionary">
    <property name="dictionaryPath"
     value="the name of the dictionary file 
           for example <your_training_folder>/etc/<your_model_name>.dic"/>
    <property name="fillerPath" 
     value="the name of the filler file 
           for example <your_training_folder>/etc/<your_model_name>.filler"/>
    <property name="addSilEndingPronunciation" value="false"/>
    <property name="allowMissingWords" value="false"/>
    <property name="unitManager" value="unitManager"/>
  </component>

when i make a corpus file and using online tool then it creates .dic and .lm
file but no filler file. I want to ask how can i make filler file. Is filler
file is just a text file(.txt file)? or i have to create it with some tool?
Thanks

fields file also just a text file(.txt file) in which sentence is written and
your voice path is mention with each sentence.

I suggest you to read demo example

Filler dictionary goes together with acoustic model
