Processing Libraries

Running ttstest example sketch on Mac results in ClassCastException.

ClassCastException: class com.sun.speech.freetts.en.us.cmu_time_awb.AlanVoiceDirectory cannot be cast to class com.sun.speech.freetts.VoiceDirectory (com.sun.speech.freetts.en.us.cmu_time_awb.AlanVoiceDirectory is in unnamed module of loader com.sun.speech.freetts.DynamicClassLoader @6d861d6a; com.sun.speech.freetts.VoiceDirectory is in unnamed module of loader ‘app’)

Code:
import guru.ttslib.*;

TTS tts;

void setup() {
size(100,100);
smooth();
tts = new TTS();
}

void draw() {
background(255);
fill(255);
ellipse( 35, 30, 25, 35 );
ellipse( 65, 30, 25, 35 );
fill(0);
ellipse( 40, 35, 10, 10 );
ellipse( 60, 35, 10, 10 );
noFill();
arc(50,50,50,50,0,PI);

}

void mousePressed() {
tts.speak(“Hi! I am a speaking Processing sketch”);
}

I tried using Processing 3.5.4 - installed the library through the contributions manager and ran the library example and it worked.

The library is very old and I suspect that it has not been updated for Processing 4 :cry:
