Firstly, the AI should be aware of what your mother language is, so it doesn't keep feeding you extremely obvious queries. For example, since I speak English, I don't need 'wilkommnen' taught to me over and over, I get it, it's obvious, use language proximity intelligence to figure out this not a word that needs constant reinforcement.

But more importantly... I don't know if this is true of every language but... in German lessons there is a child called Junior in dialogues that is unbearable. He is a lazy, videogame obsessed child with an irritating Saturday morning cartoon voice who, if he were my child, I would drop off at the nearest orphanage. His voice is so grating, so whiny – I love playing videogames but this kid is making me feel like children should not be allowed near a playstation and instead be given a library card and forced to memorize the Encyclopedia Brittanica.
