CMU Sphinx / Forums / Sphinx4 Help: How to use the other acoustic models from sourceforge.net?

Carlos Antunes - 2014-01-25

Hello all,

There is a document called "How to use Models from SphinxTrain in
Sphinx-4" which I am using to try to make sense out of it.

It seems that the en-us.tar.gz is a better database than the HUB4.

From Sphinx-4 build.xml file we have:

     <property name="wsj_name" value="WSJ_8gau_13dCep_16k_40mel_130Hz_6800Hz"/> <property name="wsj_data_dir" value="models/acoustic/wsj"/> <property name="wsj_8kHz_name"

value="WSJ_8gau_13dCep_8kHz_31mel_200Hz_3500Hz"/>
<property name="wsj_8kHz_data_dir" value="models/acoustic/wsj_8kHz"></property>

<property name="tidigits_name"

value="TIDIGITS_8gau_13dCep_16k_40mel_130Hz_6800Hz"/>
<property name="tidigits_data_dir" value="models/acoustic/tidigits"></property>

The build all command creates the jars for them.

Now, at http://sourceforge.net/projects/cmusphinx/files/Acoustic%20and%20Language%20Models/
you have other language models.

When you download, say en-us.tar.gz, you have a bunch of files inside
but then you need to have a jar like those above built when you
compile Sphinx-4.

So, first off is, what is the advice you can give on how to build that
and also how to proceed on the configuration of Sphinx-4 to use that.

I am using the Application Programmer Guide as sample as well as other
documentation but I would appreciate any pointers.

Thanks,

Carlos.

Generic en_US model only works with hl-interface branch. It doesn't work with any other sphinx4 branch or with a release.

You can checkout hl-interface branch from subversion, see the tutorial for details

http://cmusphinx.sourceforge.net/wiki/tutorialsphinx4

You do not need to put the model into jar to use it, you can just specify a model folder in the source code.

Application manual is outdated.

  Hi Nickolay,
  I can't manage to find this hI-interface branch you're mentionning in this thread. I looked over the branches and tags on the SVN but it doesn't stand out. Any link?

    That branch has been already merged, use trunk.

      Got that one firgured out in between. Last issue on my side: using this high level interface, I cannot change the logLevel, can I? (I only load the lib through maven, so I do not have direct access to default.config.xml).
      
      As a sidenote, I'm using the HL API because I can't get the us-english-generic models to work with the config file.

        LogLevel has nothing to do with default.config.xml. You can change it
        through the call to the Java standard API. Read
        http://cmusphinx.sourceforge.net/wiki/tutorialsphinx4 to learn how to
        use custom XML configuration.

Thanks Nickolay! Yes, I did download and built the hi-interface branch.

I still have a few questions which I am not clear.

Now the questions are related to the en_US model properties. I do not know what which values to adjust here:

<property name="relativeBeamWidth" value="1E-60"/> <property name="absoluteWordBeamWidth" value="22"/> <property name="relativeWordBeamWidth" value="1E-30"/> <property name="wordInsertionProbability" value=".2"/> <property name="languageWeight" value="10.5"/> <property name="silenceInsertionProbability" value=".1"/> <property name="acousticLookahead" value="1.7"/>

Also, I would like to add them under my /src/main/resouces/model/ folder so that I can generate a JAR with Maven. I want the models to be part of the JAR.

If I do so, can I do something like this: "resource:/model/language_model.DMP" using the resource:/ in front?

Also, HUB4 for instance comes with a Model.class. I do not see any Model.class on the other Language Models for download here.

Form the examples, you have:
<component name="hub4" type="edu.cmu.sphinx.model.acoustic. HUB4_8gau_13dCep_16k_40mel_133Hz_6855Hz.Model">
<property name="loader" value="sphinx3Loader">
<property name="unitManager" value="unitManager">
</property></property></component>

If I an to use the en_US language models, then shall I skip that? I imagine I still need the sphinx3Loader as that model much have been trained with sphinx3. Correct?

Thank you!

You shouldn't adjust any of these

Yes

Model class is not needed for a long time

If I an to use the en_US language models, then shall I skip that? I imagine I still need the sphinx3Loader as that model much have been trained with sphinx3. Correct?

No, please read the tutorial first

  Thanks again Nickolay,
  
  I have been reading (and I have printed) all the tutorials. You are
  referring to "Sphinx-4 Application Programmer's Guide" under
  http://cmusphinx.sourceforge.net/wiki/tutorialsphinx4 which has one
  page and uses the WSJ model as the example?
  
  Looks like it is slightly different from the last time I have played
  with it. That is the confusion for me then.
  
  I will try that.
  
  Cheers.
