I've had a number of requests for the sound demonstration I presented at the recent ASA meeting in Honolulu, in which the spoken phrase 'sometimes behave so strangely' following several repetitions, appears convincingly to be sung rather than spoken - though there is no musical context and no physical transformation of the sound. This demonstration, together with spoken commentary, is on my CD 'Phantom Words and Other Curiosities' (available from Philomel Records -
