roger that, thanks for your input, with all the advancement on ai and speech synthesis i thought it would be easier by now.
while it still would sound fairly monotone, in a game where all characters are robots, not only it would work in my tests it can be hilarious. and of course there's no need for any recording, just type your text, add some pauses here and there and it works.
im surprised not many companies use this, the only one that comes to mind lately is The Finals but that is obviously another level of quality.
