Regarding the fast talking and lip syncing problems with Japanese animation dubbed into English:
In the process of creating American animation, the script is read and recorded, then the animators create the lip and facial movements according to what is said and its inflection.
In the process of creating Japanese animation, the animation is created first with all of the facial expressions. This is because the animation has manga (comic book) roots. Then, the voice talent watches the animation and attempts to synchronize the script with the action.
This is why they may seem to talk fast in Japanese, and even faster in the English dub. Or why there is terrible lip syncing.
In animation, time is money and there is a price on each frame. Save a frame, save a buck. Hence the sometimes jerky motion.
Bet you didn't think you would learn something today.
Here, have a little fun. Watch any current anime, but turn down the sound. Look at the characters lips. Pretty simple huh? Sure, there are raised eyebrows and open eyes every once in a while, and an occasional circular mouth to show excitement.
Now watch current high quality American animation, if you can find it, and look at the mouths. The movements are a little better.
Now watch some real old American stuff, from the 30's and 40's. The mouth movements are so good, you can read their lips!
