I am new to freetts and I want to convert text to speech, but I am getting class not found exception.

My source code

package com.sewonet;

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

public class App {
    public static void main(String[] args) throws Exception{
        VoiceManager voiceManager = VoiceManager.getInstance();
        Voice voice = VoiceManager.getVoice("kelvin16");
        voice.speak("I love java");
    }

}

Code compilation does not generate any error but generate the below error at runtime.

Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/speech/freetts/VoiceManager
        at com.sewonet.App.main(App.java:7)

You need to make sure that that class is on the classpath when you run your program. – tgdavies Jan 02 '23 at 03:20
Please I am using maven and I have specified the freetts 1.2.2 dependency in the pom.xml file. – eritten Jan 02 '23 at 03:26
How are you running your program? – tgdavies Jan 02 '23 at 04:07
