McCoys Voice Change?

Has anyone else noticed McCoys change of voice when he meets Rachael
at the Tyrell Building (1st time)

"Its Damn Weird?"

The voice seems to be the same, but the volume is at higher level. The voice of rachael and Tyrell is louder too, i guess that the whole conversation is recorded in one file...

I replayed that part of the game again... And I see your point,it is almost definatley higher.
