Harry Potter and the Voices in My Head

I'm currently on page 600 of the new Harry Potter book, and I can now answer with certainty the burning question I posed a few posts back. The voice of Snape in my head is pretty much the same as the one my brain conjured up for him in previous books, though it takes only a tiny (and occasionally involuntary) shifting of mental gears and he immediately slides into Rickman's voice instead. Which actually makes for some rather strange effects...

Oh, and Umbridge, the new Defense Against the Dark Arts professor, is really making me wish I couldn't hear characters' voices, because hers is insanely annoying. Gahh.
