Yeah, you’d just have to extract them from the films with as little background noise as possible. I’m sure if somebody was dedicated enough they could isolate his lines from the audio mix, but I’m just not up for that myself.
Also, it’s not a problem for me to “work” on this. For some reason, I find AI generators super fun to mess around with, and the best part is all of this has only cost me 1 dollar so far.
