How Would I Get This Desired Effect?

Hello everyone, I am working on an experience right now and I was wondering how I would get this desired face effect on the NPC.

Thanks for the help in advance ill be gone for a bit

Probably a surface GUI, with the eyes and stuff being images. Then just scale the Y size of the things depending on the output volume of the Sound object.

There are many face packs on roblox and various animation plugins allow you to animate them such as moon animator, that’s my guess on how they pulled off this effect.
