The McGurk effect

I would like to ask you to participate in a little audio experiment.

Please start playing the clip below but I would like to ask you not to watch it but to listen to it. So please have your eyes shut…


Now what is he Saying?

BA BA BA ???

Now I like to ask you to play the clip again but now you can open our eyes.


So what was he saying?

Most people think they are hearing DA DA DA..

This is a so called fused respons- where the D is a result of and audio visual illusion. In reality you are hearing the sound “BA”

While you are seeing the lip movements “GA GA GA”

You have just experienced the “McGurk effect”, and I like this example so much because it clearly demonstrates that there are more things happening within an audio and visual context.
