No voice output

Question

I'm using VOCE library(https://sourceforge.net/projects/voce/) for speech synthesis in Java with netbeans for an application and below is the code.

public class synthesisTest{
public static void main(String[] argv){

    voce.SpeechInterface.init("../../../lib", true, false, "", "");

    voce.SpeechInterface.synthesize("This is a speech synthesis test.");
    voce.SpeechInterface.synthesize("Type a message to hear it spoken " 
        + "aloud.");

    try
    {
        String s = "Hey testing";
        voce.SpeechInterface.synthesize(s);
        voce.SpeechInterface.stopSynthesizing();
    }
    catch (Exception ioe)
    {
        System.out.println( "error:" + ioe );
    }

    voce.SpeechInterface.destroy();
    System.exit(0);
}
}

However when I run this code the output is

[Voce] Initializing synthesizer
[Voce] Initialization complete
[Voce] Shutdown complete
BUILD SUCCESSFUL (total time: 0 seconds)

but no voice output. However it is giving output if the string is read from console. How to fix this as I want this to work for the string provided in the code?

Answer 1

You call

voce.SpeechInterface.synthesize(s);

That starting the speech

voce.SpeechInterface.stopSynthesizing();

From documentation: "Tells the speech synthesizer to stop synthesizing. This cancels all pending messages. "

Then the speech is immediately stopped.

You must wait the end of the speech without forcing to stop it. This must done in a loop else the application end before the speech.
