java - InputStream 和 URL 不兼容

Question

我在 Eclipse Helios Java 1.6 中工作。我已经下载了 CMU Sphinx-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();
    }
}

行内错误:

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);
}

如何解决这个兼容性问题？代码取自here

从 Helios 转移到升级版本或 Java 1.6 到更高版本可能代价高昂，因为很多以前的代码都是在 Helios 和 Java 1.6 上编写的。

该方法需要一个 InputStream 作为参数，您不能传入一个 File 或一个 URL 来代替。

只需传入一个InputStream:

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