Jsapi speehc synthesizer and recognizer

Question

Hello friends, Have any one of u done a project on speech synthesizer and recognizer using jsapi and Freetts...???

Answer 1

(contd..) to previous thread step5
//testing
u can find so many examples in the net though iam giving one below!!
Class name is Main.java
code follows
package tts; // my package
import java.util.Locale;
import javax.speech.Central;
import javax.speech.synthesis.Synthesizer;
import javax.speech.synthesis.SynthesizerModeDesc;
import javax.speech.synthesis.Voice;
import java.io.*;
import java.lang.*;

public class Main {
* @param args the command line arguments
public static void main(String[] args) {
System.out.println("args==" + args.toString());
String voiceName = (args.length > 0)
? args[0]
: "kevin16";
voiceName = new String("kevin16");
System.out.println("Voice Name is :" + voiceName);
//System.out.println("Using voice: " + voiceName);
try {
System.out.println("---1---");
/* Find a synthesizer that has the general domain voice
* we are looking for. NOTE: this uses the Central class
* of JSAPI to find a Synthesizer. The Central class
* expects to find a speech.properties file in user.home
* or java.home/lib.
* If your situation doesn't allow you to set up a
* speech.properties file, you can circumvent the Central
* class and do a very non-JSAPI thing by talking to
* FreeTTSEngineCentral directly. See the WebStartClock
* demo for an example of how to do this.
SynthesizerModeDesc desc = new SynthesizerModeDesc(
null, // engine name
"general", // mode name
Locale.US, // locale
null, // running
null); // voice
System.out.println("--2--");
Synthesizer synthesizer = Central.createSynthesizer(desc);
/* Just an informational message to guide users that didn't
* set up their speech.properties file.
System.out.println("--3--");
if (synthesizer == null) {
System.out.println("--3(1)--");
// System.err.println(noSynthesizerMessage());
System.exit(1);
System.out.println("--4--");
/* Get the synthesizer ready to speak
synthesizer.allocate();
synthesizer.resume();
/* Choose the voice.
desc = (SynthesizerModeDesc) synthesizer.getEngineModeDesc();
Voice[] voices = desc.getVoices();
Voice voice = null;
System.out.println("Length :" + voices.length);
for (int i = 0; i < voices.length; i++) {
if (voices.getName().equals(voiceName)) {
voice = voices[i];
System.out.println("voice " + voice);
break;
if (voice == null) {
System.err.println(
"Synthesizer does not have a voice named " + voiceName + ".");
System.exit(1);
synthesizer.getSynthesizerProperties().setVoice(voice);
System.out.println("going 2 play");
/* The the synthesizer to speak and wait for it to
* complete.
//synthesizer.speakPlainText("Hello world!,iam vijay testing Freetts", null);
String str = new String("heloo world");
System.out.println("String is ....: " + str);
synthesizer.speakPlainText(str, null);
synthesizer.waitEngineState(Synthesizer.QUEUE_EMPTY);
/* Clean up and leave.
synthesizer.deallocate();
System.exit(0);
} catch (Exception e) {
e.printStackTrace();
// TODO code application logic here
@Override
protected Object clone() throws CloneNotSupportedException {
return super.clone();
@Override
public boolean equals(Object obj) {
return super.equals(obj);
@Override
protected void finalize() throws Throwable {
super.finalize();
@Override

return super.hashCode();
@Override

return super.toString();
here we are using Kelvin16 as voice type..
still u have any problem during the running ... let me know
