What is reassuring about reading aloud? What does reading aloud accomplish for us that reading silently to ourselves does not?
For myself, when I read aloud, I always notice things I missed when I read silently. It could be an error in the sentence construction which causes me to stumble over a word, or an emphasis placed in a certain area of the sentence. Sometimes I can sense a depth of emotion present in the way I say the words as I am reading them.
I have found that reading my own work aloud allows me to revise and edit my work to a greater extent and thereby increase the chance that readers will correctly interpret what I am endeavoring to convey. Is it wise to say that I am my own best critic? No, but it certainly feels that way when I read my work out loud.
