Really fun is trying to do various accents and seeing what it thinks you sound like, I tried my best South African and it thought Japanese. Guess I need to work on my mimicry
I'm half South African and can do many of the different accents, notably Afrikaans, Cape Town (white and coloured) and black SA, they're all very different. I'm pretty sure most people think of Wickus v.d. Merwe from District 9, but that's not the only one!
I can also speak a bunch of other languages without accent so good luck for any AI to fit me in a box :P
