Read out Loud to become Smarter!
Reading out loud has important benefits. When you read out loud, your energy and focus is on what you are reading; thus you have no distractions. You strengthen your mental and verbal skills. New words become part of your vocabulary when you speak them aloud. Reading aloud improves your memory and you remember spoken words better than ones read in your mind.
Caution : Avoid it in libraries or else you might be termed as a lunatic!
