InputStream与URL不兼容

Question

我在EclipseHeliosJava1.6中工作。我下载了CMUSphinx-4并添加到Java项目中。下面的代码是将音频文件转换为文本文件。

import java.io.File;

import edu.cmu.sphinx.api.Configuration;
import edu.cmu.sphinx.api.SpeechResult;
import edu.cmu.sphinx.api.StreamSpeechRecognizer;

public class AudioToText {
    public static void main(String [] args){
        Configuration configuration = new Configuration();

        // Set path to acoustic model.
        configuration.setAcousticModelPath("C:/Program Files/eclipse/sphinx4-5prealpha/models/acoustic");
        // Set path to dictionary.
        configuration.setDictionaryPath("C:/Program Files/eclipse/sphinx4-5prealpha/models/acoustic/wsj/dict/cmudict.0.6d");
        // Set language model.
        configuration.setLanguageModelPath("C:/Program Files/eclipse/sphinx4-5prealpha/models/language/en-us.lm.dmp");

        StreamSpeechRecognizer recognizer = new StreamSpeechRecognizer(configuration);
        recognizer.startRecognition(new File("D:/audio.mp3").toURI().toURL());
        SpeechResult result = recognizer.getResult();
        recognizer.stopRecognition();
    }
}

错误是一致的：

recognizer.startRecognition(new File("D:/audio.mp3").toURI().toURL());

错误：

- The method startRecognition(InputStream) in the type StreamSpeechRecognizer is not applicable for the 
 arguments (URL)
- The method startRecognition(InputStream) in the type StreamSpeechRecognizer is not applicable for the 
 arguments (File)
- Line breakpoint:AudioToText [line: 19] - main(String[])

当我查看startRecognition()定义时，

public void startRecognition(InputStream stream) {
    recognizer.allocate();
    context.setSpeechSource(stream);
}

如何解决此兼容性问题？代码取自这里

从Helios转换到升级版本或Java1.6到更高版本可能会很昂贵，因为许多以前的代码都是在Helios和Java1.6上编写的。

该方法需要一个InputStream作为参数，您不能传入一个File或URL。

简单地传递一个InputStream

recognizer.startRecognition(new FileInputStream("D:/audio.mp3"));
