Definition of Speech-to-song illusion

The speech-to-song illusion is an auditory illusion discovered by Diana Deutsch in 1995. A spoken phrase is repeated several times, without altering it in any way, and without providing any context. This repetition causes the phrase to transform perceptually from speech into song. Though mostly notable with languages that are non-tone, like English and German, it is possible to happen with tone languages, like Thai and Mandarin.
