These days, newly published books often get promoted with video trailers, and there's one that just came out for Michael Erard's Babel No More: The Search for the World's Most Extraordinary Language Learners. In keeping with the book's theme of hyperpolyglottery, Erard rounded up speakers of different languages to create a multilingual reading of a story told in his book. (Direct link here — that's me at 1:05.)
And there's a contest! Here are the details from the trailer description:
How good are you at identifying spoken languages? I asked friends from all over to say one line of a story about Cardinal Giuseppe Mezzofanti, and all the lines are assembled here. Send an email message with 1) the name of each language and 2) in the order in which they appear to email@example.com, and I'll put your name in a drawing for a signed copy of Babel No More. Deadline is February 23.
I'll keep the comments closed until the deadline to keep anyone from divulging the names of the languages. Good luck!
Update, 2/12: I've replaced the original version of the trailer with a corrected one.
Update, 2/23: Here is the video with the languages indicated.
