If your goal is to communicate power, set the pitch, tone, volume, and tempo of your voice in the following ways: Pitch and tone: The lower, more resonant, and more baritone your voice, the more impact it will have. Volume: One of the first things an actor learns to do on stage is to project his voice, which means gaining the ability to modulate its volume and aim it in such a targeted way that specific portions of the audience can hear it, even from afar. One classic exercise to hone your projection skills is to imagine that your words are arrows. As you speak, aim them at different groups of listeners. Tempo: A slow, measured tempo with frequent pauses conveys confidence.
