Currently I am working on Speech recognition using Sphinx. I added my own grammar file and appended to dictionary too. But I am getting NullPointer Exception Error which is shown below

Loading... Exception in thread "main" java.lang.NullPointerException at edu.cmu.sphinx.model.acoustic.WSJ_8gau_13dCep_16k_40mel_130Hz_6800Hz.ModelLoader.loadProperties(ModelLoader.java:372) at edu.cmu.sphinx.model.acoustic.WSJ_8gau_13dCep_16k_40mel_130Hz_6800Hz.ModelLoader.getIsBinaryDefault(ModelLoader.java:386) at edu.cmu.sphinx.model.acoustic.WSJ_8gau_13dCep_16k_40mel_130Hz_6800Hz.ModelLoader.newProperties(ModelLoader.java:346) at edu.cmu.sphinx.util.props.ConfigurationManager.lookup(ConfigurationManager.java:214) at edu.cmu.sphinx.util.props.ValidatingPropertySheet.getComponent(ValidatingPropertySheet.java:403) at edu.cmu.sphinx.model.acoustic.WSJ_8gau_13dCep_16k_40mel_130Hz_6800Hz.Model.newProperties(Model.java:158) at edu.cmu.sphinx.util.props.ConfigurationManager.lookup(ConfigurationManager.java:214) at edu.cmu.sphinx.util.props.ValidatingPropertySheet.getComponent(ValidatingPropertySheet.java:403) at edu.cmu.sphinx.linguist.flat.FlatLinguist.setupAcousticModel(FlatLinguist.java:204) at edu.cmu.sphinx.linguist.flat.FlatLinguist.newProperties(FlatLinguist.java:167) at edu.cmu.sphinx.util.props.ConfigurationManager.lookup(ConfigurationManager.java:214) at edu.cmu.sphinx.util.props.ValidatingPropertySheet.getComponent(ValidatingPropertySheet.java:403) at edu.cmu.sphinx.decoder.search.SimpleBreadthFirstSearchManager.newProperties(SimpleBreadthFirstSearchManager.java:183) at edu.cmu.sphinx.util.props.ConfigurationManager.lookup(ConfigurationManager.java:214) at edu.cmu.sphinx.util.props.ValidatingPropertySheet.getComponent(ValidatingPropertySheet.java:403) at edu.cmu.sphinx.decoder.Decoder.newProperties(Decoder.java:71) at edu.cmu.sphinx.util.props.ConfigurationManager.lookup(ConfigurationManager.java:214) at edu.cmu.sphinx.util.props.ValidatingPropertySheet.getComponent(ValidatingPropertySheet.java:403) at edu.cmu.sphinx.recognizer.Recognizer.newProperties(Recognizer.java:93) at edu.cmu.sphinx.util.props.ConfigurationManager.lookup(ConfigurationManager.java:214) at demo.sphinx.helloworld.HelloWorld.main(HelloWorld.java:49)
