CMUSphinx从不识别音频文件中的任何单词

Sphinx似乎无法识别或处理音频文件，它接受音频流会吐出一个空数组（SpeechResult结果）。我觉得我正在使用的音频文件没有任何问题，因为我已经尝试了几次，但对任何一个都不起作用。有没有人知道他们可以正常工作的音频文件？并且有什么引人注目的可能导致流不产生转录的东西吗？

public static void main(String args[]) throws IOException {
    Configuration configuration = new Configuration();
    configuration.setAcousticModelPath("resource:/edu/cmu/sphinx/models/en-us/en-us");
    configuration.setDictionaryPath("resource:/edu/cmu/sphinx/models/en-us/cmudict-en-us.dict");
    configuration.setLanguageModelPath("resource:/edu/cmu/sphinx/models/en-us/en-us.lm.dmp");

    StreamSpeechRecognizer recognizer = new StreamSpeechRecognizer(configuration);
    //recognizer.startRecognition(new FileInputStream("E:/1video/hello-5.mp3"));

    File file = new File("E:/1video/bargain_not.wav");
    FileInputStream fis = new FileInputStream(file);
    InputStream is = new FileInputStream(file);

    //is = AutomaticSpeechRecognition.class.getResourceAsStream("/edu/cmu/sphinx/demo/aligner/10001-90210-01803.wav");
    recognizer.startRecognition(is);
    SpeechResult result = null;
    while((result = recognizer.getResult()) != null) {
        System.out.println(result.getResult()); 
        System.out.println(result.getHypothesis());

        System.out.println(result.getWords()); 
    }
    //result = recognizer.getResult();
    //System.out.println(result);
    //System.out.println(result.toString());
    //System.out.println(result.getWords());
    /*for (WordResult wordResult : result.getWords())
    {
        System.out.println(wordResult);
    }*/
    recognizer.stopRecognition();


}

这是运行它的输出-它似乎没有任何故障
