在java语音识别sphinx循环中启用按钮启用按钮API

Question

我正在用AWT框架创建一个基本的语音识别Java API。 我完成了我的编码，我的API也正在运行，但现在我想在识别正在进行时在我的API中引入“停止”按钮。 我正在尝试在语音识别开始后使此Stop按钮有效。 但我无法这样做。 我想打破停止按钮点击识别的while循环，而不是让while循环无限。 请帮我出您的建议.. 我的主类是：

package com.ongraph; 

import java.awt.BorderLayout; 
import java.awt.TextArea; 

import java.awt.event.ActionEvent; 
import java.awt.event.ActionListener; 
import javax.swing.JButton; 
import javax.swing.JFrame; 
import javax.swing.JLabel; 
import javax.swing.JPanel; 

public class SpeechRecognizer extends JFrame { 

    /** 
    * Main class of the Application. Contains the UI of Application. 
    */ 
    private static final long serialVersionUID = 1L; 

    final JFrame frame = new JFrame("Speech To Text"); 
    final JPanel panel = new JPanel(); 
    final static JPanel panel_First = new JPanel(); 
    final JPanel panel_Second = new JPanel(); 
    final JPanel panel_Third = new JPanel(); 
    final static TextArea textArea = new TextArea("", 10, 60); 
    final JButton speak = new JButton("Speak"); 
    final static JButton clear = new JButton("Clear"); 
    final static JButton stop = new JButton("Stop"); 
    final BorderLayout borderLayout = new BorderLayout(); 
    final static JLabel stop_Command = new JLabel(
      "Speak 'Stop' to Stop Recording."); 

    final static SpeechToTextOperation speechToTextOperation = new SpeechToTextOperation(); 

    public static void main(String args[]) { 

     new SpeechRecognizer(); 

    } 

    public SpeechRecognizer() { 
     speak.setEnabled(true); 
     clear.setEnabled(true); 
     stop_Command.setVisible(false); 
     textArea.setVisible(true); 
     stop.setEnabled(false); 

     // When ever Speak button is pressed this method is invoked. voiceGet() 
     // method of SpeechToTextOperation class is called in this. 

     speak.addActionListener(new ActionListener() { 
      public void actionPerformed(ActionEvent ae) { 

       speak.setEnabled(false); 
       try { 
        speechToTextOperation.voiceGet(); 
       } catch (InterruptedException e) { 
        // TODO Auto-generated catch block 
        e.printStackTrace(); 
       } 
      } 
     }); 

     // When ever Clear button is pressed this methos is invoked. It clears 
     // the TextArea only after the Application has been stopped. 
     clear.addActionListener(new ActionListener() { 
      public void actionPerformed(ActionEvent arg0) { 
       // TODO Auto-generated method stub 
       speechToTextOperation.voiceStop(); 
       textArea.setText(""); 
       speak.setEnabled(true); 
      } 
     }); 
     frame.add(panel_First, BorderLayout.NORTH); 
     frame.add(panel_Second, BorderLayout.CENTER); 
     frame.add(panel_Third, BorderLayout.SOUTH); 
     panel_First.add(speak); 
     panel_First.add(stop); 
     panel_Second.add(clear); 
     panel_Third.setLayout(borderLayout); 
     panel_Third.add(stop_Command, BorderLayout.CENTER); 
     panel_Third.add(textArea, BorderLayout.SOUTH); 
     frame.setSize(600, 400); 
     frame.setVisible(true); 
     frame.setDefaultCloseOperation(EXIT_ON_CLOSE); 
    } 
} 

有狮身人面像代码的类是：

    }

Answer 1

您可以创建在您的主一个public static boolean isStart;和引用它为您while循环。

因此，而不是使用while(true)你可以使用类似while(main.isStart)。 然后只需设置isStart = false;当停止按钮是按下，并设置isStart = true;然后当开始按钮是按下。

您应该始终避免在您的代码中使用while(true)，这很可能是更好的方法。
