我通过Sphinx在JAVA中创建了一个关于语音识别的项目。我的代码执行得很完美但是当我通过“runnable jar file-＆gt;将所需的库复制到子文件夹”创建它的jar，并通过命令“java -jar {jar name} .jar”通过cmd执行它时它会打开但是之后选择说话按钮或调用sphinx方法，它会发现错误edu.cmu.sphinx.jsapi.JSGFGrammar类未找到。 我没有办法解决这个问题。 我对文本代码的发言是：
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：

总体而言，最好使用最新版本5prealpha和http://cmusphinx.sourceforge.net/wiki/tutorialsphinx4
中描述的API至于你的例外，它说没有找到班级。您需要将该类打包到jar中才能运行代码。包名称也可能有所不同。最近，edu.cmu.sphinx.jsapi包被重命名为edu.cmu.sphinx.jsgf。您可能有问题需要更新。
