Sound file - hear most of the pitch-tracked examples, as pronounced by Aditi Lahiri, in .wav format. This is an old cassette that I recently found and digitized (2008). They're probably not exactly the same examples as in the paper, but they are close and might be useful in giving readers an idea of what these intonation contours sound like.
