I made a rig for my actors face but what I'm missing now is creating the individual mouth positions and emotions. Now what goes for the emotions I can tape myself so that's not an issue. My main problem now are the mouth positions. I figured out so far that I need to look for what is called a "viseme" and that when I have all of them posed that I have all I need to make some speech happening. My problem now is though that I somehow can not find anywhere on the Internet a list of all visemes in the English (preferably also German but that's not so important right now) and how they look like (that I could do myself I guess once I know what to look for).

So has anybody an idea where I can get a list (and optionally look) of all visemes in the English language?
