Shows following error on running Sphinx 4 on wsj model files

[Suman Saurabh]

I have copied acoustic models in /tmp/acoustic/ folder dictioanry model in /tmp/cmudict.0.6d and language model in /tmp/en-us.lm.dmp

On running the code it shows following error: "java.lang.AssertionError: duplicate property-name for different properties: grammarLocation"

This issue must be fixed in trunk, please update.

[Nickolay V. Shmyrev]

And, we recommend you to use en-us generic acoustic model, not wsj, it provides way better accuracy.

Thanks Nick, I will be using 'en-us' for acosutic, cmusphinx-5.0-en-us.lm.gz for language and cmudict.0.7a for dictionary.

I am using OSS Repository of Sphinx4 and issue has not been fixed in repository. Sphinx can do the recognition but fails in junit test cases.

<dependency>
    <groupId>edu.cmu.sphinx</groupId>
    <artifactId>sphinx4-core</artifactId>
    <version>1.0-SNAPSHOT</version>

Hey Suman

I've updated sphinx4 packages on OSS, please try again. Let me know if there are any issues.
