Dialogue: giving each character a unique voice

iving a character a unique voice creates a vivid mental image of a person because speech is a form of characterization. Word choice, grammar, cursing and even silence, it all says something about the sort of person.

Note: this goes for major characters only. It is not necessary to give a distinct voice to background characters or minor characters with only one or two speaking lines.

Content variation

Personality affects speech

Dialogue is filtered through your personal perception and preoccupations.

Associations are personal. The words people use to describe something stems from their personal experience. This includes use of metaphors.
Example:
Chef – “That paint is flour white.”
Gambler – “Don’t tell your wife, you can’t show her your cards!”

Personality further affects speech content. They each have a favourite expression.

Each person has their own way of saying hello (with or without nicknames) which may differ if speaking to a loved one or stranger.
Example: The womanizer calls every woman ‘darling’ right from the start. “Hello, darling.”
Example: Father to daughter: “Hello, peanut.”
