Hello Guys and Gals

I am trying to create a vary very basic speech recognition application in Java.  Has anyone got any tips, tricks or know of any useful resources that will help me in this area.

I would be grateful for any help.  

Cheers

YOU HAVE TO USE JSAPI.

The following code shows how to create a recognizer, load the grammar, and then wait for the user to say something that matches the grammar. When it gets a match, it deallocates the engine and exits.

--------------------------------------------------------------------------------
import javax.speech.*;
import javax.speech.recognition.*;
import java.io.FileReader;
import java.util.Locale;

public class HelloWorld extends ResultAdapter {
     static Recognizer rec;

     // Receives RESULT_ACCEPTED event: print it, clean up, exit
     public void resultAccepted(ResultEvent e) {
          Result r = (Result)(e.getSource());
          ResultToken tokens[] = r.getBestTokens();

          for (int i = 0; i < tokens.length; i++)
               System.out.print(tokens[i].getSpokenText() + " ");
          System.out.println();

          // Deallocate the recognizer and exit
          rec.deallocate();
          System.exit(0);
     }

     public static void main(String args[]) {
          try {
               // Create a recognizer that supports English.
               rec = Central.createRecognizer(
                                   new EngineModeDesc(Locale.ENGLISH));
               
               // Start up the recognizer
               rec.allocate();
     
               // Load the grammar from a file, and enable it
               FileReader reader = new FileReader(args[0]);
               RuleGrammar gram = rec.loadJSGF(reader);
               gram.setEnabled(true);
     
               // Add the listener to get results
               rec.addResultListener(new HelloWorld());
     
               // Commit the grammar
               rec.commitChanges();
     
               // Request focus and start listening
               rec.requestFocus();
               rec.resume();
          } catch (Exception e) {
               e.printStackTrace();
          }
     }
}

The applet works fine using JDK, its just I want to open it using a browser.  I simply open the html code and its not there. I have checked the case letter of the class.
Do you think that it is the classpath ???
