I'm barely familiar with KKPE, I've been dabbling with studio only recently and figuring out how all this works. I've attached a scene that I found in a mega recently that incorporates this effect. Not a single person on pixiv uploaded the scene data so I don't have many other ways, I have 2 other scenes that have this effect but have audio that can't be muted in the sound menu and can only be muted by muting the game.
The first scene doesn't have any sounds, the others do. But all are using a very similar effect but with different mouth morphs for the most part.
Furthermore, using these tags on pixiv

I don't even care that I may not use it, but for some reason I'm extremely curious how people are doing this and I want to know.
