You can also go back and forth to hear different vowel sounds. Because of another machine learning model, the blobs can respond to your input in real time and bring it into harmony. To change the pitch, move the dots up and down. or, if the vowels are different, back and forth.
Using another method of machine learning, blobs can respond to your input and sing in harmony with it in real time. You don't need any apps to play the game on your iPad, PC, or phone; just open any browser. You don't have to know how to play music to make your own tune that sounds like opera.
