>>> I'm not Henrik, but I've done some lip-synch stuff for Disney. We did it pretty much the way Eric described--we just used amplitude. It's not as accurate as Disney would demand on a film, but it's ok in the kids' game market.
>>> I see, amplitudes could be just good enough for some stuff. Although the "speed" and the intensitiy of the speech could give misleading results, I think. I'm under the impression that you should somehow try to compare the shape of the waves (somehow simplifiy your input to some value of sets of values that are easier to compare, possibly in a "time window") and compare it in some meaningful way to precalculated samples to find a matching pattern. That's the part I have no clue about! Cheers Juan Pablo Califano 2010/6/3 Kerry Thompson <al...@cyberiantiger.biz> > Juan Pablo Califano wrote: > > > Wow.
