Hi I'm using VOCE library in my application as I need both speech synthesis(using freeTTs) and speech recognition(using sphinx4). 

Here is my speech recognition code 

public class recognitionTest{
public static void main(String argv){
 
        voce.SpeechInterface.init("C:/Users/NetBeansProjects/src", false, true, 
        "file:/C:/Users/src/grammar", "words");
 
        System.out.println("This is a speech recognition test. " );
 
        try{
        String s="";
        s = voce.SpeechInterface.popRecognizedString();
        System.out.println("You said: " + s);
 
        if(s.equalsIgnoreCase("log in")){
                       StartApplication.count=1;
          }
          else if(s.equalsIgnoreCase("sign up")){
                        StartApplication.count=2;
            }
             else{
                        //do nothing
              }
 
       voce.SpeechInterface.destroy();
      }
       catch (Exception e)
        {
           System.out.println(e);
        }
    }
   }

I call this from another java application called StartApplication and in this I continuously check whether the value of count has changed to 0 or 1 and if not main method is called again.

However when I say login it is recognized and the value of count is changed to 1 but the following exception is generated .

Following is the StartApplication code snippet,

public void mouseClicked(MouseEvent e) {
  try{
  while(count==0)
  recognitionTest.main("");
 
  if(count==1){
      LoginPage.main();
  }
  if(count==2){
      SignUpPage.main();
  }
  }catch(Exception ee){System.out.println(ee);}
}

What I have tried:

Inorder to avoid this I removed this voce.SpeechInterface.destroy(); Now when I call this from some other application it throws the following exception

'SEVERE microphone Can't open microphone line with format PCM_SIGNED 16000.0Hz, 16 bit, mono, 2 bytes/frame, big-endian not supported.
in edu.cmu.sphinx.frontend.util.Microphone:open-microphone
