I'm disappointed, I was hoping this was going to be about Coach McGurk from Home Movies.

What about that classic phenomenon whereby someone reads instructions for an exercise and upon completion of said exercise swears they heard it correctly as mentioned in the original instructions?

Freeeaky. I heard BA while listening, GA while watching.

Me too, mimi; I couldn't make myself hear "da da", but definitely perceived a different sound when I had my eyes shut.

This is the coolest and strangest thing I have seen (and heard, and fused) in a long time.

Mars, it's actually 'ba ba', so it's good you couldn't force it into 'da da'

I'm confused, how can you say "ba ba" without using your lips? Secondarily, how many typos can they fit into one small paragraph of text and still expect me to take them seriously?

I think the audio was dubbed in afterwards, pejamo.

All I heard was Tom Brokaw saying "LA LA LA LA LA LA"
or:
"GA GA GA GA GA GA"

Right... hence the effect.

I once saw this effect demonstrated in front of an audience of a few hundred people, as part of a seminar on developmental linguistics. The speaker's point was that language has many visual cues associated with it, so in teaching language to infants, it's important to have a native speaker who can accurately reproduce those cues, along with the proper phonetics. Infants can't learn language properly from an audio recording.
Anyway, when she gave this demonstration (video of the speaker, projected hugely at the front of the room), you could hear collective gasps and giggles coming from the audience as people opened and closed their eyes. Single most impressive demonstration I've ever seen as part of a scientific talk, I think.

Amazing! Slightly off-topic, but inattentional blindness is another cool example of how our brains warp and filter reality (no video unfortunately).

Very interesting. I heard "ba ba" and "da da" like most people. My wife on the other hand heard "ba ba" with her eyes closed and "ga ga" with her eyes open.
She has limited hearing in one of her ears. So it makes sense that she'd rely more on the visual input.

I have perfect hearing, but the recording sounded exactly the same to me with my eyes open or closed: "ba ba".

I covered the guy's mouth up and kept watching his eyes, and heard ba ba. I moved my finger away and it immediately sounded like da da (the moment I saw his lips.) I hear da da even if the guy is on my peripheral, and have to close my eyes or turn my head completely to hear the ba-s.
How freeeeeeeeeeeeaky.

Banished, I am so clearly hearing a 'tha tha,' as well. This is really incredible. It's one thing to be fooled the first time, but what amazes me is even after closing my eyes and knowing that it is really 'ba ba' with my eyes open again I still hear it wrong. I mean, I'm hearing it. Like the tha/da sound is coming into my ears. The effect even works if I glance away from the screen during the video.

Incidentally, the difference between ba ba and ga ga is what's stopping the airflow from the lungs -- in ba ba, it's the lips, in ga ga, it's the center of the tongue. Obvious to some, but I had _no_ idea of tongue shaping before linguistics class. Didn't even realize the basic stuff, like the identical nature of f/v, s/z, t/d, etc... they're spoken the same, it's just if our throat buzzes or not. Feel your mouth move.
The McGurk effect probably has alot to do with the fusion of sensory signals at the LGN -- the laternal genticular nuclei. Basically, our optical and auditory nerves merge at this small nut shaped region, and are joined by nerves from all over the rest of the brain. IOW, there are feedback loops that modify our sensory signals _before they're even analyzed_. Thus the very strongly perceived auditory shift based on lip motion -- I mean, it's not just that we understand differently, it really feels like the voice says something different when we close our eyes.

It sounded like a deaf person saying da da, to me. Lots of Gallaudet students around my neighborhood, so maybe I'm just used to hearing that. But it makes sense, in that they are producing sounds they haven't heard.
