Imitate the voices of famous actors or fictional characters. Learning to imitate a sound can help you build flexibility, recognize pitch and tone, and give you good material to include on your demo reel. You don’t have to be an impressionist to be a voice artist, but it is helpful to be able to change the sound of your voice. This will allow you to be more versatile and will also help with your acting skills. Try to match not only the person’s voice, but also their personality so that you bring them to life rather than just imitating their sound.
