Do yourself a favor when you make a mistake in the middle of reading your voiceover script – take a nice slow breath. Think of your breath as a palate cleanser. You don’t want to jump right back in to your audition in “mess-up mistake mode.” Breathe, and reset your gears. You will now go back in to your performance with a clear mouth and mind. Let go of the anxiousness to instantly correct your mistake because this will continue the energy in the same direction. Breathe. Start again.
