Estill Voice Training

Estill Voice Training (EVT) is a science-based vocal instruction system that breaks down voice production into independent, isolated muscle movements to give singers and speakers total control over their sound. Developed by singer and researcher Jo Estill in 1988, it shifts vocal training away from vague, classical imagery (like "sing from your diaphragm" or "place the sound in your mask") and replaces it with concrete, anatomical reality.
