here is a very poor gif version of the video:

It looked so much better than lipsync made with switches, It made me think about how you could emulate this animation using smart bones. I traced a character and created some smart bones. Of course I'm not as good animator as the one who made this tests, but the rig construction took me around three hours and it's incredible flexible and easy to use:

The animation is 24fps, but the mouth is animated in intervals of 3's and the eyes are on 2's.
Here you can check the file

This test was made without any planning, but now I'm thinking about which smart bones targets would be necessary to get as much freedom as possible using as few bones as possible. If anyone have an idea, please don't hesitate write it.
