An actor is a person who plays a role (or part) in a drama, such as a play, a movie, or a television program. A female actor may be known as an actress, although the term "actor" is also used as a gender-neutral term.
An actor usually plays a fictional character.
A voice actor speaks a part but is not seen by the audience. This may happen in a radio play. Voice actors are also used in animation, to represent the voices of cartoon characters, and in computer games.
