Java Expert for Text to Speech using FreeTTS

I am in immediate need of a Java programmer to improve the voice of the open source library FreeTTS,
using the default voice (kevin) is too robotic, I am looking for a programmer that can set a custom voices, like Google TTS etc. where I can choose few from the proposal

I am attaching the default code, and the library to include


import com.sun.speech.freetts.Voice;
import com.sun.speech.freetts.VoiceManager;

public class TextToSpeech {

// kevin or kevin16
private static final String VOICENAME_kevin = "kevin16";

public static void main(String args[]) {
TalkResource("This is Tokyo. FLIGHT arrival and departure information. Alpha AT 0 7 2 4 Runway in use 3 1 transition");
}

public static void TalkResource(String sayText) {
System.setProperty("freetts.voices", "com.sun.speech.freetts.en.us.cmu_us_kal.KevinVoiceDirectory");
Voice voice;
VoiceManager voiceManager = VoiceManager.getInstance();
voice = voiceManager.getVoice(VOICENAME_kevin);
voice.allocate();
voice.speak(sayText);
}
}


I am looking for something with few high quality voice:

import com.sun.speech.freetts.Voice;
import com.sun.speech.freetts.VoiceManager;

public class CustomVoiceExample {
public static void main(String[] args) {
// Set the path to the custom voice data
String voicePath = "/path/to/custom/voice";

// Initialize VoiceManager
VoiceManager voiceManager = VoiceManager.getInstance();

// Load the custom voice
Voice customVoice = new Voice(voicePath, Voice.VOICETYPE_GENERAL);

// Register the custom voice with the VoiceManager
voiceManager.registerVoice(customVoice);

// Allocate the custom voice
customVoice.allocate();

// Set properties for the custom voice (if needed)
customVoice.setVolume(100);
customVoice.setRate(150);

// Speak using the custom voice
customVoice.speak("Hello, this is a sample text using the custom voice.");

// Deallocate the custom voice when done
customVoice.deallocate();
}
}
