You can actually improvise a lot as a voice actor. It's not that entirely different than shooting a live action movie; the characters mouths are quite easy to manipulate once all the information is built into the computer. So you can improvise a lot and it doesn't matter really how far along they are in the process they can really just make the character say something different.

I realized - I don't know if you're familiar with "Karate Kid," but the bad guys in that are called Cobra Kai, and they're, like, the evil karate guys. And then when I went to the tournament, I realized that's what we were; we were like the Cobra Kai of the Jewish karate community.
Seth RogenI always thought realistic was a better way to explain things that were "dramedies" because life is like that. It's funny, it's dramatic and to me that's how I see it.
