This book is based on the presentations at the 3rd International Conference on Speech Motor Control and Fluency Disorders. Much more than than the former proceedings this book brings together in a fairly comprehensive way a unique collection of theory and experimental work in the area of speech motor production and fluency disorders. Many chapters present overviews of recent progress in our knowledge about a large range of topics: speech production models, motor control in speech production and fluency disorders, brain research in speech production, methods and measurements in pathological speech, developmental aspects of speech production and fluency disorders. Everyone who is interested in the field of speech motor production in general as well as in fluency disorders, be it as a scientist, clinician or student, will find useful information in this book for both research and teaching purposes.
