Harry potter sorting hat

Hi I got a harry potter sorting hat cheap and want to us a wemos d1 mini to control its motor so it's mouth will move to any audio source. Help would be apreciated thanks

Bubble, quick, heap or merge?

Phoneme recognition requires much processing power. Dunno about tiny algorithms :frowning:

There's a lot more to mouth movement than volume to make it look not horribly fake and off. That also accounts for muppet-style mouth movement.
