Maybe I'm just crazy, but to try it, I DID NOT read the words before ... and I definite heard one of the two word. Then I decided to focus on one of the words, and I still heard the other one!
When I rewinded the clip few times, my brain was focused enough I think, and I started hearing the word I was reading, But it does not work every time. At least not for me.
yes its a weird one! for me it worked perfect the first 10 times.. then suddenly i got stuck on one.. and couldnt hear the other! I think it depends how you are feeling.. i discovered if i do it when i just wake up my mind is dozy and it works even better!
the mind is strange!@
