<p>I deleted another post I made because I wasn’t really offering any helpful advice to the OP (and now I’m making another pointless post :() But basically I wanted to say that I thought about it a bit more, and tried reading a little to make sure… and started to think that I really don’t subvocalize at all. I can understand how doing it would slow you down. (I got a 36 on Reading, if it matters). The more you read and practice, the less you subvocalize, but it’s probably a very slow learning curve. One trick you can try is to look at a page of text line by line, instead of word by word. Move your eyes across the page just a notch faster than you would if you were just reading naturally. That will encourage your brain to process the words more quickly so that your reading comprehension catches up to the movements of your eyes. As your reading speed increases, subvocalization most likely naturally decreases. Fast readers can read much more quickly than anybody can speak, which makes the “voice in your head” scenario impossible… so it simply disappears.</p>
<p>Also, realize that when you’re reading stuff on the ACT, you’re not supposed to be reading as quickly as you would read a fiction novel for pleasure. You should read slowly enough to absorb all of the information so you can answer questions about it later. Even for some people who don’t subvocalize naturally, slowing down their speed to that extent means they start to subvocalize a little bit. I’m sure people can get 30+ scores on reading even with subvocalization, so don’t stress about it.</p>
