Intonation is becoming increasingly prominent in areas from phonology to speech recognition. Ladd gives an exceptionally clear overview of the key ideas of Pierrehumbert's autosegmental-metrical theory to intonational phonology, and discusses alternative approaches. He also looks critically at the version put forward by generativists, and offers his own solutions. This book will appeal to phonologists as an original contribution, and will be welcomed by students and researchers, who will find in it the ideal overview of recent work.
