"Voice" is about the author's style of presenting his/her story.

My point was that how those elements are presented, are referred to by most agents and publishers as "authorial voice".

I think that anyone who has been confused by an editor's negative or positive reaction to "voice" in a given manuscript or published work, thinking perhaps the editor was referring to a character, should have that confusion cleared up rather quickly when reading this thread!
