Lip Syncing in Maya

I have always thought it very fascinating that technology had brought us so far to be able to lip sync characters. I am very interested in learning this type of thing in Maya even though I know it will be much harder than it looks. It is so complex from the colors used, the eye movements, the way the body moves just like a human would, to the intricate mouth movements. It is very motivating to watch when you are in the beginning of a class on 3D. I am interested to see what the steps are to create a final piece like this.
