I tried to get the mouth shapes for the various words that the character has to say, but then I realised that I was making more work for myself because I would then have to adjust all the key frames on the time slider for the various facial muscles to fit them in the correct time frame.

This time, I added the audio into the maya scene and adjusted the time slider so that I would be focused on one word at a time, ensuring the timing was correct before moving on to the next word.
There’s already a clear improvement from the first attempts, however, it noticeably falls out of sync towards the end. I had been so focused on moving the lips that I forgot that the chin moves as well when people speak, so when I went back to add it in, it interfered with the lip movements.
The book cited below really helped to plan out and then improve my lip sync, although, when I only got it after I had initially got the rough shapes, so I used it to tweak the movements.
I’m going to start again, so there is a good foundation to build upon.
