Words translate into imagery usually, I have no inner voice then.
I can turn on an inner voice, but then there's no imagery. I'd need to pause, go over the words in my mind again to get the mental video running.
If the text doesn't have relating imagery to begin with, I read with an inner voice.
I'd also re-read this post with an inner voice, because I need to translate what goes on in my head into words and have my inner voice say them to write them down anyway.
Reading without an inner voice = faster. Because then I don't need to wait up for words to be transferred into sounds.
As for the test, those are numbers! That won't necessarily work on people with issues with numbers. I test excellent at that because my spontaneous association with 5 is the word/spelling "five". Not the abstract meaning of 5.
And ah, I'm not dyslexic! Probably hyperlexic actually.
