The best-selling voice therapy text on the market, The Voice and Voice Therapy enters its eighth edition with extensive revisions, including thoroughly expanded content, updated pictures and figures, and improved teaching pedagogy elements. In addition, the new edition includes an updated DVD that brings voice problems and therapy to life for students. Still the most complete voice treatment textbook available, The Voice and Voice Therapy boasts the most up-to-date evidence-based practice and outcomes assessment and voice therapy facilitation techniques available today, while the comprehensive companion DVD illustrates voice problems in children and adults, as well as methods of relevant therapy, enabling students to see and hear what they are reading about. The eighth edition divides voice disorders into four causal areas (psychogenic, muscle tension, organic, and neurogenic), with each identified issue presented with particular evaluation procedures and strategies. The text also covers disorders that are not often addressed in other books-including sulcus vocalis, muscle tension dysphonia, and paradoxial vocal fold dysfunction.
