Java Speech API: Changing the voice

[Yohan Weerasinghe]

Hi, please have a look at the following code, which I found in a book web site

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();
		}
	}
}

I don't have the MBROLLA voices, so this code is not working (I tried to install mbrola, but that is not working too. The software is updated while the definition, documentation, guidance are not!). The only way to make this work is changing the voice to "kevin16" the default voice. Is there any way to set that voice to the previous application? I can do that by the following code,

    VoiceManager voiceManager = VoiceManager.getInstance();
             
        voice = voiceManager.getVoice(VOICENAME);

but it destroyed the use of "Synthesizer " class which most of the examples are based. So, I must use the "Synthesizer " class to too because it is a good way to make my application powerful. Please help....
