synesthesia

I know someone who has this - where he hears music and sees colour.

SPOILER BELOW... if you want to listen and watch for yourself, you can
read this after you're done...

The interesting thing about what occurred when I watched:

1. neat, neat?, peat, peat. neat, neat, peat, peat
2. neat, neat, peat, peat. neat, neat, peat, peat

Note "neat?" is where he says people hear "meat." I /did/ think I
heard meat, but it sounded too nasalised, and I was very very confused
by the fact the lips didn't match perfectly what I was hearing. It
was like it was out of synch or something. At first I figured I heard
him wrong, began comparing what I'd seen to his voice as I watched the
next word come forth, couldn't figure out why the sound was off so
badly that it didn't match the sound correctly, and ultimately
concluded that he'd said "neat." I based this on context, because he
never said he was going to say "meat" but /had/ mentioned the word
"neat" and repeated it later on.

After I got myself all confused, I found myself reading below as I
listened to and half-watched the second part, and realized he /had/
said "neat" and that he was superimposing his speech on top of an
original recording of "neat, peat, neat, peat."

So: In short, I /did/ do what he said most people do, but due to the
synchronization problem, I wasn't 100% certain I heard him correctly.
Then I pulled a CAPD compensation and found "neat" was the only
obvious word he could have used in that strange context, so I fixed
what I heard with what I thought I should have heard.

If he /had/ said "meat" with the same synchronization issue, I likely
would have gotten that wrong, especially after I'd heard the whole
thing.
