i think i operate very similar to you, at least WRT to the devouring-whole-sentences when reading fiction. emai;/IM/LJ is definitely "flavored" by the personality of the person i'm reading, and that flavor may have something to do with voice, but i'm not doing anything like "hearing" the voice in my head. it's almost more like speaking it.

of course, this is one of those centipede's dilemma or "don't think about a white horse" heisenburg things, where observing how i do it changes how i do it...
