Roodaka counts number of fingers she has on her right hand, 4 to be exact.
Also, my first time animating fingers and speech. Hooray.
The voice sounds odd since I use automated voice on the web, mainly because I can’t sound like a female.
The movement is linear from shut to open and back. Think about how the chin actually moves when you pronounce different words, and have the model imitate that wag in more detail. I doubt you actually wish to move the pieces by stretching them like rubber or actual flesh; just focus on the chin movement as it’s the only mechanical movement in speech you can properly imitate within your limitations.
