Exception in thread “AWT-EventQueue-0” javax.speech.EngineStateError: Invalid EngineState

[Kavya]

Hi
I'm using VOCE in netbeans. This is my 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);
    }
}

}`

When I run this I got the following exception.

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 16000.0 Hz, 16 bit, mono, 2 bytes/frame, big-endian not supported.
in edu.cmu.sphinx.frontend.util.Microphone:open-microphone
Cannot start microphone.'

How to fix this?

We only support sphinx4, not voce.

[Kavya]

Voce uses sphinx4

[Nickolay V. Shmyrev]

We do not support voce. If you have any question on sphinx4, in particular on latest version http://cmusphinx.sourceforge.net/wiki/tutorialsphinx4, let us know.
