Lipsync with phonem animations?

In relation to the code provided here.

My 3D model has the transform of the mouth broken into 8 mouth transforms and the jaw. I modified this code to an array for the jaw and the bottom part of the mouth which looks right, but I guess the top isnt moving(which your mouth doesnt do) it looks wierd.

I tried using the animation portion provided, but I get wierd results. I have several phonem animations set up, but I have no experience in this area. When I used the PhonemO for making an O sound I get a wierd result from the code provided in which the mouth stretches out and crisscrosses. The model actually even has emotion phonems happy, angry,etc.

So, guess my question is how would I use this code with the Phonems or should I just be figuring out how to use the Phonems completely different than this method? Thanks for pointing me in the right direction.
