A description of the problems that people can experience with their voices, either by vocal misuse, psychological and physical stress, laryngeal pathologies or neurological disorders. Chapters are contributed by clinicians who have a special interest and expertise in voice disorders and their management and treatment. Two strong themes are clearly identifiable in each chapter: the first is the emphasis on the physiological aspects of phonatory dysfunction, and the second is the recognition that vocal impairments can have significant social and psychosocial consequences. Many of the contributors have also addressed issues such as evidence-based practice, efficacy and the outcomes of intervention.
