Ancient Egyptology - Isis, Usir and Aset?

Egyptologists aren't sure how ancient egyptians actually pronounce the names, because hieroglyphics don't include vowels. Experts think that isis might have been pronounced aset and osiris usir,. Well, when in cairo, you know, you mean when in menefer, right? So anyway, you might expect that these two, usir and aset, would go to the party together. But aset was off doing something else, because she was way too smart to be attending a function hosted by usir's brother seth.
