Voice actors are professionals who provide the voices for characters in various media, including animated films, television shows, video games, and commercials. They use their vocal skills to bring characters to life, conveying emotions and personality through their voice alone. This work often requires versatility, as voice actors may portray a wide range of characters, from animals to humans. Many voice actors also participate in dubbing, where they replace the original voice in a foreign film or show with their own. Notable voice actors include Mel Blanc, known for his work with Looney Tunes, and Tress MacNeille, famous for her roles in The Simpsons.
