Not there yet... Worse than a dubbed film.
Its an interesting idea. But this app so far is like Siri several years ago. Itll get there one day. Matching facial movements, lip movements and more with actual spoken words is tough. Id wait around until a handful of more versions have come out. Currently its much worse than any dubbed karate movie.
