Amazing Transformation From Speaking To Singing

The amazing speech-to-sound illusion:

First listen to Sound Demo 1. Your brain will interpret it as a melody. Then listen to Sound Demo 2. In the middle of the speech the speaker will appear to burst into a song!

To experience the illusion, play the two recordings in sequence
(demos by Diana Deutsch, UC San Diego).

The speech-to-song illusion reveals that the exact same sequence of sounds can seem either like speech or like music, depending only on whether it has been repeated.

  1. That's pretty bizarre Rob. I had to listen to them a couple times to get the effect.

  2. Wow that is pretty bizarre alright. Now if ever I listen to only the second sample I hear that song. I wonder now, if I did not know the "tune" what the second demo would sound like? Very cool!

  3. I understand what I'm meant to hear, but I don't hear it. It must be my old brain. I shall persevere.

    1. Yeah, it is really more of what I would refer to as "talking in a 'sing-song' voice;" at first it sounds like normal speech but when repeated it starts sounding unnaturally melodic.( At least for me anyways...) Hang in there mate - if my brain'll do it you should be optimistic for yourself. ;)

    2. Thanks for the encouragement masodo, but it not happening. I might come back in a few days and have another go.
