do you normally have an inner voice and just suppress it when reading quickly? or not have one at all?

wondering as I lack one so curious if it's also worth trying to develop it in the other direction

you lack one as in while reading or general? For me I have to supress it and force myself to read in "fast mode" where I purposely look at the words and try to understand them without sound. I read about it in some speed reading guide and started practicing it and it does seem to work. But it still baffles me that we can just straight up get information without having to speak it out or verbalize it internally. That is pretty insane to me
