Take acting classes or find an acting coach. This will help you to develop your acting talent. Though voice actors never appear on the screen, they must be extremely talented actors in order to effectively deliver their lines. Remember that in some ways, voice acting is more difficult than other types of acting because you don't have other actors to work off of and the audience can’t see your facial expressions, hand gestures, or movements. You don’t have props or other tools to aid in your delivery. Your full emotions and personality must be expressed solely through your voice.
