Cory Whelan, BA (George Washington University), Doody's Review Service, (2009): "The clinician manual describes how clinicians should conduct eight therapy sessions using LMRVT. It covers taking a complete case history, stretching exercises, and the core resonant voice exercises. The best part of the clinician manual is that it outlines exactly how the treatment should be carried out. It moves from stretches and simple humming to practice words and chanting. The exercises get more complex as the program advances, and the manual tells the clinician exactly in what order to proceed."
