I just made a variant of this that uses the browser speech recognition API. It's simplified, with none of the flair of the original, but should be fun to play in person. It's fun to shout animal names at computer with friends.
Super fun, I'd love to get a little bit more time like in the OPs website for each animal that I guess right. Instead of 1 second, it should be something like 6 because I can speak much much faster than the speech recognition is able to separate out my guesses.

(works best on desktop chrome. it's too slow on safari in my testing.)
