Research

Estill studied various qualities associated with different styles of singing, using techniques including EMG, electroglottography, voice signal analysis, X-rays of the phonating larynx, laryngeal fibre endoscopy, acoustic measurements and simultaneous videostroboscopy. This led to the development of a series of exercises to develop specific control over individual muscle groups and structures in the vocal mechanism. For example, Estill's endoscopic video recordings of the vocal tract during voicing demonstrated deconstriction techniques such as the 'silent laugh' that encourage the false vocal folds to retract. These exercises are now included within the Estill Voice Training
