Now Cory:

This is an interesting thought; I had actually viewed the use of the 
fact that Snape spoke the AK in a different light.

Because we know that Snape is proficient at performing nonverbal 
spells, we can assume that he *could* have performed the AK 
nonverbally if he had chosen to do so.  I assume the reason why he 
spoke the incantation is because he wanted the Death Eaters who were 
present to *know* that the spell he performed was, in fact, an AK.  
Alternatively, JKR may have wanted *us* to know that the curse was 
an AK, thus eliminating any doubt as to whether Dumbledore is 
really, truly dead.
