"This will become the next ‘go-to’ textbook for off the shelf and up to date guidance that is relevant to the vast array of children, young people and adults who benefit from AAC."" - Janice MUrray, Department of Health Professions, Faculty of Health and Education, Manchester Metropolitan University ""The book is accessible and unique in its focus on explanations rather than on simply recipes on ""how to do it"". It provides accessible yet sound reasonings behind the choice of particular form of AAC or sets of intervention strategies."" -Gloria Soto, Professor, Department of Speech, Language and Hearing Sciences, San Francisco State University ""...the text can fill an important gap in highlighting the life-time impact of developmental disorders and the changing role of AAC across all life stages... I anticipate that it will become a key reference in most programmes where AAC is a curriculum focus..."" -Martine M. Smith, Professor Clin. Sp. & Language Studies, School of Linguistic, Speech & Communication Sciences, Trinity College Dublin."
