Improvise in character. Doing improvisation is an important skill in voice acting because directors will expect this of you. This skill will allow you to truly embody a character and think like they do. After you’ve gotten into character, try coming up with a funny story on the spot as that character. If you need help, have a friend ask you questions and respond based on what you think the character would say. For example, if you are doing an impression of Kermit the Frog, you could make up a story about asking Miss Piggy out on a date.
