The Kate sounds a lot better than the Nick (who has that robotic gravel to his voice) but I think that there is some question as to how much better would it act

The Kate sounds a lot better than the Nick (who has that robotic gravel to his voice) but I think that there is some question as to how much better would it actually be with more data: If trained on longer samples does it start to hallucinate? Learning programs are notorious for rough approximations failing to scale into useful detail. Very cool work though!
