Apparently, 99% of people asking for that kind of thing won't do it themselves. And tbf, I have no idea what language this Taung guy would speak. If its basic (Human), then we'd need a voice actor with a good mic and a low voice. Not very easy to get. Then there's the developing part. Good luck with that too lol
It would be great indeed. Unfortunately, as the community is quite restricted nowadays, because of the game's age, you'll likely never find someone who'll do that for you, unless they're a super Taunt fan. That being said, you can always learn how to mod the game and do it yourself !
