Last week, I heard a very engaging story on NPR about voiceover artist Daws Butler, the creator of vocal personalities for many cartoon characters, including Yogi Bear, Smedley, and Quick Draw McGraw, among others. The NPR audio piece showcased Daws' method for teaching voice acting, with snippets from recordings he had made over the years illustrating his technique. Daws, who was self-taught as a voice actor, developed a physical technique for creating voices, based on his belief that if he could look like a character, he could sound like that character, too. If you have the time to listen, it's worth it--especially if you have good memories of Hanna-Barbera cartoons.
