I read aloud to my children a lot. When I'm reading to myself I mostly don't read aloud unless it's poetry. I also sometimes read my own writing aloud as part of the editing process.
I read in my head but I do love reading aloud to children or sharing a particular interesting item with whomever is with me at times. It is nice to share reading a newspaper that way I think. I will read my writing out loud as this is a really helpful tool when editing. If you can't speak it out loud fluently then it is not well written.
