Java 基于sphinx的语音识别
目前我正在使用Sphinx进行语音识别。我添加了自己的语法文件并附加到字典中。 但我得到的是NullPointer异常错误,如下所示 加载。。。 线程“main”java.lang.NullPointerException中出现异常 位于edu.cmu.sphinx.model.acoustic.WSJ_8gau_13dCep_16k_40mel_130Hz_6800Hz.ModelLoader.loadProperties(ModelLoader.java:372) 位于edu.cmu.sphinx.model.acoustic.WSJ_8gau_13dCep_16k_40mel_130Hz_6800Hz.ModelLoader.getIsBinaryDefault(ModelLoader.java:386) 位于edu.cmu.sphinx.model.acoustic.WSJ_8gau_13dCep_16k_40mel_130Hz_6800Hz.ModelLoader.newProperties(ModelLoader.java:346) 位于edu.cmu.sphinx.util.props.ConfigurationManager.lookup(ConfigurationManager.java:214) 位于edu.cmu.sphinx.util.props.ValidatingPropertySheet.getComponent(ValidatingPropertySheet.java:403) 位于edu.cmu.sphinx.model.acoustic.WSJ_8gau_13dCep_16k_40mel_130Hz_6800Hz.model.newProperties(model.java:158) 位于edu.cmu.sphinx.util.props.ConfigurationManager.lookup(ConfigurationManager.java:214) 位于edu.cmu.sphinx.util.props.ValidatingPropertySheet.getComponent(ValidatingPropertySheet.java:403) 位于edu.cmu.sphinx.linguist.flat.FlatLinguist.setupaudionicmodel(FlatLinguist.java:204) 位于edu.cmu.sphinx.linguist.flat.FlatLinguist.newProperties(FlatLinguist.java:167) 位于edu.cmu.sphinx.util.props.ConfigurationManager.lookup(ConfigurationManager.java:214) 位于edu.cmu.sphinx.util.props.ValidatingPropertySheet.getComponent(ValidatingPropertySheet.java:403) 位于edu.cmu.sphinx.decoder.search.SimpleReadthFirstSearchManager.newProperties(SimpleReadthFirstSearchManager.java:183) 位于edu.cmu.sphinx.util.props.ConfigurationManager.lookup(ConfigurationManager.java:214) 位于edu.cmu.sphinx.util.props.ValidatingPropertySheet.getComponent(ValidatingPropertySheet.java:403) 位于edu.cmu.sphinx.decoder.decoder.newProperties(decoder.java:71) 位于edu.cmu.sphinx.util.props.ConfigurationManager.lookup(ConfigurationManager.java:214) 位于edu.cmu.sphinx.util.props.ValidatingPropertySheet.getComponent(ValidatingPropertySheet.java:403) 位于edu.cmu.sphinx.recognizer.recognizer.newProperties(recognizer.java:93) 位于edu.cmu.sphinx.util.props.ConfigurationManager.lookup(ConfigurationManager.java:214) 位于demo.sphinx.helloworld.helloworld.main(helloworld.java:49) 如何解决这个问题……我的语法文件是Java 基于sphinx的语音识别,java,speech-recognition,sphinx4,Java,Speech Recognition,Sphinx4,目前我正在使用Sphinx进行语音识别。我添加了自己的语法文件并附加到字典中。 但我得到的是NullPointer异常错误,如下所示 加载。。。 线程“main”java.lang.NullPointerException中出现异常 位于edu.cmu.sphinx.model.acoustic.WSJ_8gau_13dCep_16k_40mel_130Hz_6800Hz.ModelLoader.loadProperties(ModelLoader.java:372) 位于edu.cmu.sph
