My husband doesn't even have an internal voice! Thought he was joking but it's A Thing. He gets the words translated straight into images, like in a play when a spotlight illuminates character or scenery as it's described.

This sounds insane to me but we got into the discussion because he didn't know why I needed to turn down the car radio to find the right house number first time we visited an address. He didn't realise I don't process the "8" I see until my brain says "eight" internally.
