CMU Sphinx

Hello,

I am new to Sphinx4 (1.0beta2) and am trying to run a test class (which is pretty much the same code as the hellodigits demo class.

The problem is that I receive the following error:

Property Exception component:'flatLinguist' property:'grammar' - mandatory property is not set!
edu.cmu.sphinx.util.props.InternalConfigurationException
at edu.cmu.sphinx.util.props.PropertySheet.getComponent(PropertySheet.java:283)
at edu.cmu.sphinx.linguist.flat.FlatLinguist.newProperties(FlatLinguist.java:186)
at edu.cmu.sphinx.util.props.PropertySheet.getOwner(PropertySheet.java:421)
...

I see the following message in System.out:

class not found !java.lang.ClassNotFoundException: edu.cmu.sphinx.jsapi.JSGFGrammar

I can't seem to figure out where to find this class. It is not in the sphinx4.jar or any other jars that are in the sphinx4 distribution as far as I can tell. I would really appreciate any help that might be offered. Thanks.

Regards,

Joe
