Ask HN: Do you read aloud or silently in your minds?

Most times while reading a new topic that I am not familiar with, I tend to read aloud in my mind. Yet that changes based on the content and the way it is written.

When I'm focused, I notice that reading silently helps increase my reading speed and cognition, like everything is flowing in.

Other times I don't seem to understand anything if I'm not reading it aloud in my mind.

Has anyone noticed such a thing and if so can you share any tips or information you've learned about this behavior
