You write your words.
You silently read your words.
You edit your words.
You silently re-read your words.

Not only does it help you catch typos and grammar incongruities, but it enables you to hear the music of your words--the flow and sonorous quality of your writing. It helps you identify your characters' rhythms and informs you in no uncertain terms whether or not your dialogue rings true.
