Estill Voice Training

Estill Voice Training (EVT) is a scientific, evidence-based system for vocal development. Founded by Jo Estill in 1988, EVT is a life-changing approach that can help you become a stronger and more emotional performer by giving you effective tools to improve your craft.

Simple everyday sounds are used to identify structures in the larynx and in the vocal tract (throat, mouth and nose). These are then trained in detail to give conscious, predictable and reliable control of your voice in the 13 Figures for Voice.

Estill Voice Training uses a Power-Source-Filter model to explain how the voice works. Within this model there are 13 structures, which are trained independently for maximum control and freedom. The 'figure' is an exercise for conscious control of the structure. The figures are:

  1. True vocal folds; onset-offset

  2. True vocal folds; body-cover

  3. False vocal folds

  5. Cricoid cartilage

  11. Velum
