'Heyyyy, maybe I'll give you a call sometime. Your number still nine-one-one?'
So to begin all the 'ae', 'ee', 'oh' and 'you' sounds indicate the mouth with be open, while m's, v's and f's will be achieved with the mouth shut. The below animation was my first attempt at opening and closing the mouth at the right moments. I feel its out of place on the second sentence however, mainly due to the speed at which the line is spoken.
The second part of the tutorial was adding phonemes- essentially shaping the mouth so that the words can be read on the lips. This made a far more interesting looking character as things began to take shape. the resulting video is still messy, but it came out better than I thought it might.
