I've got an ant script to convert AcousticModels.tgz into msu_ru_nsh....jar suitable for sphinx4.

How can I submit it?

Thank you very much, but I don't really understand what did you got and what do you want to submit and where.

Sphinx4 can use a sphinx3 acoustic model. I order to use one, as far as I understand, it is necessary to repack the acoustic model with a new directory layout. So build.xml does this function - moves files to their new places, compiles necessary accessor classes and creates a jar file with the stuff.

If someone wants to use sphinx4 as an ASR engine, then they will have to somehow convert AcousticModels.tgz to jar format of sphinx4.

I've got both - an ant script build.xml and the result of the transformation -  msu_ru_nsh_8gau_13dCep_16k_40mel_130Hz_6800Hz.jar.

I think these can be placed in one of the following ways:

1. build.xml - goes to trunk/scripts in dev.
2. ...jar goes to the same folder as AcousticModels.tgz (downloads/russian...)
3. build.xml along with ..jar goes to downloads/Russian/Trunk/AcousticModels/sphinx4.
4. other ways.

> it is necessary to repack the acoustic model with a new directory layout

It isn't. You can just point to the model data in config file:

  <component name="model" type="edu.cmu.sphinx.linguist.acoustic.tiedstate.TiedStateAcousticModel">
    <property name="loader" value="sphinx3Loader"/>
    <property name="unitManager" value="unitManager"/>
  </component>

  <component name="sphinx3Loader"             type="edu.cmu.sphinx.linguist.acoustic.tiedstate.Sphinx3Loader">
        <property name="logMath" value="logMath"/>
        <property name="unitManager" value="unitManager"/>
        <property name="dataLocation" value="file:model"/>
        <property name="modelDefinition" value="file:model/mdef"/>
  </component>

Instead sphinx4 documentation should be updated

Ok, the next release will come with jar included.
