Its not much of an illusion to me, both mouth movements look different, and both sounds are different, the "V" doesn't sound like an "F". Maybe a different example would be better.

Interesting - had to look it up and learn more...

I think you missed the point. Yes, both mouth movements are different, however, the ACTUAL sound is the same both times. Yet, the sounds SEEM to be different, simply because the visual mouth movements are different.

If "both sounds are different" to you, then the illusion worked.

That did not make sense to me. Both sounds sounded different to me.

What illusion? Both sounds were different without seeing (at least to me).

problem is, moving the mouth different ways, the sound is actually different. it may be close, but still won't be identical. The only way they could do this with any true scientific merit would be to have the sound being made by something that isn't making the movement.

In other words record the sound and loop it, then have the video of a person making the two mouth movements in time with the recorded sound. Then it'd be convincing.

I believe that is what they did. How else could they do the side by side video.

The entire point is about listening comprehension....right?

on the speakers I have on my laptop, I couldn't hear a difference at any point, but I knew what they were talking about. The method they were trying to use (through most of the segment at least) just didn't work for me.

It was the same sound both ways, just coupled with different mouth movements. If you closed your eyes and heard a distinction, then there may be something wrong with your hearing.
