Mumbling. Speaking too fast. Nervousness. There are countless issues that can derail a public speaker. That's where Nattacia Satie and The Vocal Gym for Public Speaking come in. A musician, actress, yogi, and all-around renaissance woman, Ms. Satie uses her diverse expertise—which includes training at the University of Cambridge—to build rigorous workouts for the voice. During private sessions, she takes speakers through a four-step process that teaches proper breathing technique, incorporates core fitness exercises, and fine-tunes articulation. Ms. Satie's custom programs help her clients gain confidence and correct their specific issues by training their vocal cords to keep a steady pitch, slow down, or roll over.
