This is a complete basic course in English phonetics and phonology. Since its first publication, this course has established itself as the most practical, comprehensive text in the field and become widely used in universities and other HE institutions. This fourth edition takes into account recent developments in the teaching of phonology. It includes updated references, fuller coverage of intonation, and a new chapter on different varieties of English. Each chapter includes notes on further reading, discussion of the more challenging issues, written exercises and, where appropriate, suggestions for teachers. Accompanying audio and a full answer key are also provided. Audio files, additional exercises and other supporting material are available online.
