Use this exercise to grow and specify the poetics of a speaking voice in your story. This is especially useful if you have a character who feels generic or stereotyped.
Prep
Dial down
The visual metaphor for this is Photoshop-based. In this metaphor, color = personality. For one scene featuring the voice you’re exploring, go through and drain all the color out of their lines, dial down the existing voice. Leave a black and white line with no personality. Edit so that only the bare skeleton of the line remains. (Later you will dial the line back up, but with a new, astonishing, never before seen color.)
Questions
Interview your character with these or similar questions, oriented toward the character’s habits of thought. Answer in the first person, as the character.
What do you care about?
What gives you authority to speak?
Do you possess power? Where and how and in relation to what?
Where do you come from?
How do you know what you know; what skills or trainings have shaped you?
Look over your character’s answers. Single out a few interesting thoughts and write them on a card you can put in your line of sight while you write. Tune in to anything that surprises you, answers that spontaneously surfaced in the interview.
Resources
On a piece of paper with two columns, brainstorm two lists: temperaments (habitual mood-places for this character and a few of their opposites) and images (just brainstorm off the top of your head, an X in a Y type images that summon a picture and a feeling (a rabbit in a field, a kid at a cafeteria table).
Slow Write
With your answers from your character’s interview, your skeletal lines, and your two-column resource page in view (I literally put them next to my computer so I can look at them as I write), go back to the top of the scene and rewrite each person’s line, including those of other characters. (You may find those other characters saying new things, or you may transfer them exactly.) I STRONGLY encourage retyping every line and not cutting and pasting. The reason for this excess labor is that it gives you the chance to reconsider everything in the scene.
Before writing a line, say it. For the character whose voice you are exploring, go slowly, deliberately, and try out several versions of an utterance before committing it to paper. Continually refresh your thoughts by looking at the resources for this scene. How can the temperament offer a way of seeing this speaker in reaction or relation to the other characters in the scene? Can you borrow a mood or energy of the line from an image?
Remember, characters can be complex and they can be awkward and they can overflow or underflow or fail to complete a thought or have to say something seven times before they get it right. Don’t feel pressured to make a perfect equivalency between what a character really thinks/means and what they say.
