In essence you're looking to radio control a ventriloquist dummy.
I believe that servos can be used to articulate a number of functions that a dummy might have including controlling the eyes, eyebrows and turning the head. The movement of these features seems to be within the speed range of servos, but articulating the mouth is another matter. The speed required for the movement of the mouth is a good bit faster than the output from any servos I've seen. There are other possibilities however. Before I go any further I must explain that I have no expertise in the field that I will suggest, but I am familiar enough to think that this will work for you. What I am referring to is robotics and within that field is an item that I believe you need instead of a servo. It's called an actuator. These devices can move much faster than any servo and do not generate that much noise. It may take a bit of exploring in robotics, but I believe you'll ultimately find what you're looking for.
Good luck with your project!!!
