I personally don’t find much difference in style and voice. Both set you apart and make you unique. Both include word choice, tone, context, purpose, and sentence structure. How you craft content is your style. Voice is your unique way of saying things. An author’s written voice should be as recognizable as their spoken voice.
Clear as mud?
Well, let’s muddle things up more and pose the subject of character voice.
They have a voice, too????
Of course. It must reflect their personality and attitude. They, too, will have their own unique word choice, tone, context, purpose, and sentence structure. After a few chapters, the reader should be able to tell who is speaking in dialogue even when they haven’t been informed by a tagline of he/she said. Their speech pattern tells all.
So quit worrying about style and voice and get your words on the page. Style and voice will appear in time. You don’t have to search for them. They will find you.
