Jeff Elkins, The Dialogue Doctor, talks about building great protagonist and antagonist voices. He discusses how to build a villain voice that complements and contrasts to the hero's voice, how to use quirks to help define a character's voice, and how secondary characters can empower the change you want to make in the protagonist.
