I noticed when I'm holding a conjuration spell at the ready you can hear something... A little like whispers. When you "sheathe" the spell, I can almost make out a word... Has anyone else noticed this? And does anyone know what's being said?

I realize it's probably just a cool effect, but I also wouldn't put it past someone to put some kind of easter egg in there.

I do hear something but can't make it out. It would make sense if you're getting ready to summon something. That's a nice little addition to the conjuration.

I always assumed it to be daedric incantations, since you're summoning creatures and weapons from the planes of Oblivion.
