Earlier quoted context omitted.
This is always impressive to me, I didn't realize a thing until "tlaknig"! Although I suppose you could specifically train an AI to recogize this.
Taking the best match from a spell checker on unrecognized words will handle most of it. A threshold would probably work better against a mix of jumbled words and real gibberish.
Certainly seems doable.
Along those lines would be something like: "if I have a coin and I, err,trun tit, which face is showing?" but it's not a good example. Here "err, trun tit" gets corrected to return but the end should find to "err, turn it" instead making the face showing be "the opposite".
Hopefully you get the idea, bet there are some really good phrases that would fit this scheme.
