Estill Voice Training (also known as Estill Voicecraft) is an evidence-based system, developed by its founder, Jo Estill, a singer, educator and scientist. Estill Voice Training is used for developing control of the human voice. It offers a clear and concise vocabulary for describing vocal production mechanics and potential. The technique is science-based, objective (rather than subjectively supporting a singular style of voice production) and can be used by any voice, for any purpose, in any setting.

Estill Voice Training provides exercises designed to develop control of specific anatomical areas of voice production that contribute to the sound and feeling of the voice. Overall voice quality is the result of complex and dynamic combinations habitually acquired over a lifetime. Once this technique is learned, you can more consciously and effectively apply specific vocal qualities to your speaking and singing.

Emotional Body sponsored workshops often incorporate Estill Voice lessons taught by certified practitioners.
