It's fascinating to listen to but I wonder about extending it to other languages. Does American English lend itself well to this sort of thing or are other languages and accents reproducible. I imagine that languages with much harsher stops like German or Russian would be more difficult and those that are easily broken down, like Japanese, would be even easier than English.
