[Atul Goyal]

Hello Friends,

I want to make a java file for Text to Speech purpose.

Means user enter his name and my .class will make sound of user entered text.

Can you help me for this ?

If I were you I'd look for software that already does this and that provides an API or Software Developer Kit (SDK) that allows your Java program to utilize.

Please take the time to research the problem before you post your question. The experts here are more than willing to help you with a specific problem but you have to do your part to learn the basics.

I am using following example but it give me null pointer exception. It is not created the object of synthesis .

import javax.speech.*;
import javax.speech.synthesis.*;
import java.util.Locale;
 
public class HelloWorld {
    public static void main(String args[]) {
        try {
            // Create a synthesizer for English
            Synthesizer synth = Central.createSynthesizer(
                new SynthesizerModeDesc(Locale.ENGLISH));
 
            // Get it ready to speak
            synth.allocate();
            synth.resume();
 
            // Speak the "Hello world" string
            synth.speakPlainText("Hello, world!", null);
 
            // Wait till speaking is done
            synth.waitEngineState(Synthesizer.QUEUE_EMPTY);
 
            // Clean up
            synth.deallocate();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

Can u help me to solve this ?

Where it is throwing the null pointer exception? Please see the stack trace. And use try catch to isolate the problem.

Since i am not sure about these api i can not comment much. But look at the Java doc for corresponding api's and check the signatures etc.
