How do I use other voices when using MaryTTS embed?

I want to use MaryTTS embed in my Java application. I have downloaded the jars and put them in my classpath. I can successfully run this test:

    public static void main(String[] args) throws Exception {
        MaryInterface marytts = new LocalMaryInterface();
        Set<String> voices = marytts.getAvailableVoices();
        marytts.setVoice(voices.iterator().next());
        AudioInputStream audio = marytts.generateAudio("Hello world.");
        AudioPlayer player = new AudioPlayer(audio);
        player.start();
        player.join();
    }

The problem is that the only voice available is cmu-slt-hsmm, which makes sense because that's the only voice- jar I have in the classpath. However, I cannot find anywhere other jars for other voices, which leads me to believe I'm doing something wrong because the Mary GUI can use other voices just fine.

Solution

You need to find or create new voice jar and add this voice jar in your libs. MaryTTS does this itself using the component-installer, but i prefere to download jars manualy from official website.

Here is the list of all available voices. So, lets suppose you want to add voice-dfki-spike-hsmm. Find apropriate name in marytts-components.xml and link will usually look something like this: http://mary.dfki.de/download/5.1/voice-dfki-spike-hsmm-5.1.zip. Now you can easily unzip and put this voice to your project libs next to maryTTS source.

Demo

Set<String> voices = maryTTS.getAvailableVoices();
for(String v : voices){
    System.out.println("Voice available: " + v);
}

Result:

Voice available: cmu-slt-hsmm
Voice available: voice-dfki-spike-hsmm

If you use maryTTS GUI you probably already have all voices somewere on your hard drive. This article may help you to find them: http://myrobotlab.org/content/marytts-multi-language-support

PS. TTS voices themselves have individual licenses, so don't forget to look at it in marytts-components.xml. Usually Creative Commons, but depending on the voice's license, it may or may not be used commercially.
