As I revise my novel, I'm trying to create a consistent voice for my main character. Some of the strategies I'm using include:
1. Adopting a consistent style of writing throughout the novel that fits with my character’s background. While I’m not using a dialect (since I often find them annoying to read), my character does have certain phrases and grammatical structures that are typical of her (made up) societal group.
2. Making a conscious effort to write more simply. Though I tend to be sparse when it comes to description, I do tend to use long phrases, which may be more suitable for older age groups. This time, I’m trying to keep my sentences middle-grade short and sweet.
3. Taking time to think as my character would. Writing every day helps me slip into my character’s mind more easily. Even so, I sometimes have to stop and think about her experiences and background, to decide if what I’ve written really fits. I've had to cut sections of my novel or change elements that don't make sense in light of her past experiences or cultural background. I guess this is why we need to know as much about our characters as possible.
