@Alrik,
Basically doing lip sync, you put the voice file into your animation program, you go through it frame by frame listning to the sound and the words, and find out what the mouth should look like to match the sound/word (often using a mirror) and animate it.
Yeah, that's one way to do it... the other one would be to have an automated lip synching technique which allows more than just one voice over language. Imagine you make the English game perfectly lip synch... what is with the German/French/Italian/Spanish versions? Of course, in many cases, developers/publishers just tell the international voice over guys to take care of the lip synching - which is a hell of work while translating and recording... and: considerably more expensive than without lip synching.
Therefore, I do hope that the Larians use an automated lip synching system which somehow adapts the facial animation to the spoken words.
