I'm largely of the opposite group. Having names that aren't pronounceable helps me read code faster, as I don't try to pronounce it, and can just treat the entire word as a unit rather trying to "read" it.

I do the same in English when reading fast. I distinctly remember reading "Hermione" in Harry Potter as a child, and, because it was a name I hadn't encountered before, just "reading over" it and not thinking about the actual pronunciation. I didn't think about the actual pronunciation until some years later (probably when it was brought up in the books). Even now, if I try to pay attention to my internal monologue whilst reading, it's often words running into each other or being skipped, unless I deliberately slow down, because I'm not actively subvocalising and I'm reading faster than I would pronounce them.
