A successful cartoon voice artist needs to have strong acting skills to convey emotions and bring depth to their roles, even though their performances are typically done through voice alone. Many voice actors have a background in acting, improv, or vocal performance, which helps them adapt to a variety of styles and genres, from children's cartoons to adult animated series. The demand for voice artists has grown with the rise of animated films, TV shows, video games, and web content, leading to a competitive industry.
