how can i store output voice to an audio file in freetts

Question

I am trying to use freetts for a simple java application but i am facing a problem, can anyone tell me how can i save the output voice which is converted from text to speech into a wave file in my program. I want to do it via code.

This is the sample helloworld application which is given with the sample

import com.sun.speech.freetts.FreeTTS;
import com.sun.speech.freetts.Voice;
import com.sun.speech.freetts.VoiceManager;
import com.sun.speech.freetts.audio.JavaClipAudioPlayer;

/**

 */
public class FreeTTSHelloWorld {

    /**
     * Example of how to list all the known voices.
     */


    public static void main(String[] args) {

       // listAllVoices();

        FreeTTS freetts;

        String voiceName = "kevin16";

        System.out.println();
        System.out.println("Using voice: " + voiceName);

        /* The VoiceManager manages all the voices for FreeTTS.
         */
        VoiceManager voiceManager = VoiceManager.getInstance();
        Voice helloVoice = voiceManager.getVoice(voiceName);

        if (helloVoice == null) {
            System.err.println(
                "Cannot find a voice named "
                + voiceName + ".  Please specify a different voice.");
            System.exit(1);
        }

        /* Allocates the resources for the voice.
         */
        helloVoice.allocate();

        /* Synthesize speech.
         */


        helloVoice.speak("Thank you for giving me a voice. "
                         + "I'm so glad to say hello to this world.");


        /* Clean up and leave.
         */
        helloVoice.deallocate();
        System.exit(0);
    }
}

This code is working fine I want to save the output as a audio file on my disk.

Thanks Pranay

I figured out how to do that you have to simply use SingleFileAudioPlayer pass the file name and file type which you want sample declaration will be like:

audioPlayer = new SingleFileAudioPlayer("output",Type.WAVE);

Now you need to attach the SinglefileAudioplayer object to your VoiceManager object: e.g.

helloVoice.setAudioPlayer(audioPlayer);

Now use:

hellovoice.speak("zyxss"); 

This will save the file with whatever there in speak. Remember to close the audioplayer otherwise the file will not be saved. Put audioPlayer.close(); before exiting.

Here is the complete working code which will dump file in your C directory

I have never used FreeTTS, but a quick scan of the JavaDocs reveals Voice.setWaveDumpFile(String). Does that do what is required?
