java - 语音识别 jar 在执行时抛出错误 未找到语法类

Question

我已经通过 Sphinx 在 JAVA 中创建了一个有关语音识别的项目的 jar。我的代码执行完美，但是当我通过“可运行的 jar 文件->将所需的库复制到子文件夹”创建其 jar 并通过 cmd 使用命令“java -jar {jar name}.jar”执行它时，它会打开，但在选择后说话按钮或调用 sphinx 方法会给出错误 edu.cmu.sphinx.jsapi.JSGFGrammar 类未找到。我不知道如何解决这个问题。我的语音到文本代码是:

package com.ongraph;
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;

public class SpeechToTextOperation {
    ConfigurationManager cm;
    SpeechRecognizer speechRecognizer;
    Result result;
    Recognizer recognizer;
    Microphone microphone;
    private final static String STOP = "stop";
    private final static String XML_FILE = "helloworld.config.xml";

    public void voiceGet() throws InterruptedException {
        String resultString = null;
        int count_Check = 0;
        if (cm == null) {
            cm = new ConfigurationManager(getClass().getClassLoader().getResource(XML_FILE));
        }
        if (recognizer == null) {
            recognizer = (Recognizer) cm.lookup("recognizer");
            microphone = (Microphone) cm.lookup("microphone");
            microphone.clear();
        }
        recognizer.allocate();
        if (!(microphone.startRecording())) {
            System.out.println("Cannot start microphone.");
            recognizer.deallocate();
            System.exit(1);
        }
        instructions();
        //SpeechRecognizer.please_Speak.setVisible(true);
        while (true) {
            System.out
                    .println("Start speaking. Speak 'Stop' to Stop Recording.");
            if(count_Check == 0)
            {
                SpeechRecognizer.textArea.append("\n Start speaking...\n");
                count_Check++;
            }

            Result result = recognizer.recognize();
            resultString = result.getBestFinalResultNoFiller();
            if (resultString != null && !"".equals(resultString)
                    && !resultString.contains(STOP)) {
                SpeechRecognizer.textArea.append(resultString + "\n");
            } else {
                SpeechRecognizer.textArea
                        .append("'Application Stopped. Press 'Speak' again to restart'");
                recognizer.deallocate();
                microphone.stopRecording();
                break;
            }
        }
    }

    public void voiceStop() {
        microphone.clear();
        cm = null;
    }

    public void instructions() {
        // TODO Auto-generated method stub
        SpeechRecognizer.please_Speak.setVisible(true);

    }

}

cmd 中的错误是:

总的来说，最好使用最新版本 5prealpha 和 http://cmusphinx.sourceforge.net/wiki/tutorialsphinx4 中描述的 API

至于你的异常，它说找不到该类。您需要将该类打包到 jar 中才能运行您的代码。包名称也可能存在差异。最近 edu.cmu.sphinx.jsapi 包已重命名为 edu.cmu.sphinx.jsgf。您可能会遇到更新问题。
