Intellij IDEA IDE 运行Sphinx-4 DEMO helloworld出现空...

      最近在研究基于Sphinx-4的孤立词识别工作。原来没有接触过CMU Sphinx,所以想跟着里面的programming guide试一试。于是，在Intellij IDEA+Maven上加载了Sphinx-4库之后照着写了一个helloworld的demo同时也写好了XML文件。但是，当运行的时候显示如下的错误：

      

请各位给看看，有什么问题，还有就是有谁做过关于CMU Sphinx-4的语音识别相关工作，我有问题想要请教，多谢！

这是我的helloworld文件的java和XML文件代码：

package edu.tju.demo.sphinx.demo.helloworld;
import edu.cmu.sphinx.frontend.util.Microphone;
import edu.cmu.sphinx.recognizer.Recognizer;
import edu.cmu.sphinx.result.Result;
import edu.cmu.sphinx.util.props.ConfigurationManager;

/**
 * A simple HelloWorld demo showing a simple speech application built using Sphinx-4. This application uses the Sphinx-4
 * endpointer, which automatically segments incoming audio into utterances and silences.
 */
public class HelloWorld {

    public static void main(String[] args) {
        ConfigurationManager cm;

        if (args.length > 0) {
            cm = new ConfigurationManager(args[0]);
        } else {
            cm = new ConfigurationManager(HelloWorld.class.getResource("helloworld.config.xml"));
        }

        Recognizer recognizer = (Recognizer) cm.lookup("recognizer");
        recognizer.allocate();

        // start the microphone or exit if the programm if this is not possible
        Microphone microphone = (Microphone) cm.lookup("microphone");
        if (!microphone.startRecording()) {
            System.out.println("Cannot start microphone.");
            recognizer.deallocate();
            System.exit(1);
        }

        System.out.println("Say: (Good morning | Hello) ( Bhiksha | Evandro | Paul | Philip | Rita | Will )");

        // loop the recognition until the programm exits.
        while (true) {
            System.out.println("Start speaking. Press Ctrl-C to quit.\n");

            Result result = recognizer.recognize();

            if (result != null) {
                String resultText = result.getBestFinalResultNoFiller();
                System.out.println("You said: " + resultText + '\n');
            } else {
                System.out.println("I can't hear what you said.\n");
            }
        }
    }
}
