Estill Voice Training

Estill Voice Training (often abbreviated EVT) is a program for developing vocal skills based on analysing the process of vocal production into control of specific structures in the vocal mechanism. By acquiring the ability to consciously move each structure the potential for controlled change of voice quality is increased.

The system was established in 1988 by American singing voice specialist Jo Estill, who had been researching in this field since 1979. Estill's research led to a series of vocal manoeuvres to develop specific control over individual muscle groups within the vocal mechanism. Soto-Morettini quotes Estill as saying the great strength of her method is that it can be used for any style of music, and speech and language therapists describe the exercises as valuable to voice therapy as well as singing, in both professional and non-professional voice use, offering an approach for therapeutic intervention.
