I have an inner voice, but when I’m reading, if I’m reading something that meshes well with my brain, the inner voice is silent and I have a little movie going on in my head instead. This can be inconvenient, when my linguistic processing catches up to my imagination and I realize that there was a bit of clever wordplay or delightful phrasing I want to appreciate on its linguistic merits I have to go back and re-read it in inner voice mode instead.
