Just speak or make a noise! But it does look a bit weird. Not very realistic. But you need a mic... With this one you need a mic and a speaker which you should already have, so have fun with this one bc it imitates itself too. And... "A" for alto voice. "T" for tenor voice. "S" for squeak voice. "G" for giant voice. "K" for kitten voice. But click off the text first! Changing the volume will also change it. It will lessen the lip movements, due to less noise being detected.
Lip syncs the loudness and moves it's mouth to it! This one speaks!!! The non-speaking one: https://scratch.mit.edu/projects/407906907/ Hope you enjoy :D
