It's fun but as I tested it I realized how this is pretty much the modern equivalent of a Facebook quiz that asks you the name of your first pet, first car and mother's maiden name. If they recorded any of that they likely have enough to clone my voice somewhat faithfully. Congratulations on labelling my French Canadian accent as French though, I'll have to work on my pronounciation more to fool the AI.
It didn't guess for me other than to say I was a native speaker.
