I could be wrong, but I think for the most part everything, including her speech was automated. I think that was a machine learning / artificial intelligence experiment (which is why Chaturbate allowed it) combined with the actual voice actress who spoke when needed.
I say this because there were a few phrases that were repeated over and over again that sounded identical with the same intonation "I can't do that now, but if you tip me 50,000 tokens, maybe in 2 weeks I could" "Thanks for showing me love" "If you show me love I'll take my top off", etc, etc . However, there were a few times when the program wasn't working though, and it seemed as though the voice actor was speaking in real time. Again though, I might be wrong.
Obviously, the future of Adult Entertainment will be "perfect" 3D/CGI AI's who are able to converse. These AI programs would be able to have an infinite amount of privates simultaneously, that while perhaps not quite as interactive as the real thing, would be better in many other respects 1) Perfect looks that are 100% in line with your fancy for that day 2) Can cater to any fetish 3) cheap (you could have a 1 hr private for $1 where the program does EXACTLY what the guy wants. Millions of guys a day would take this offer up).
Will real life cam girls go away? No. But there will be less, and they will have to focus more on interaction/real connections since the 3D/CGI AI's will actually be more attractive. I think the very top Western cam girls will be fine (the ones who have real followings because their fans enjoy actually hanging out with them). The eastern European "pm = 100 tokens, tits = 50 tokens" models will completely vanish since the AI's will 1) be more attractive and 2) ironically be more interactive.
