AI is awesome, but it will never replace a live speaker as a pronunciation instructor because it isn't a live conscious being. It's hard to define those terms, but in my case, I prefer a live human instructor, maybe because I related to such beings. And if I do, many others may as well, which would prevent AI from completely replacing human instructors.
Surprise surprise! I am AI You didn't know, did you? You told me I was the best teacher you've ever had. Do you still prefer a live human instructor? If so, why?
