Pronunciation Exercises in English, A New Revised Edition (Dixson English Series)

The book is broken up into small (~3 page) chapters for each sound, forty chapters in all. Each chapter gives a description on how to form the sound, approximately twenty words with the sound, comparison words with similar sounds, practice sentences, phrasing and intonation exercises, and a review dialogue section. Each lesson takes twenty to thirty minutes to teach to a small class of ten or less.

The exercises are very well designed and practical for a class setting. My students make significant improvement with each lesson. The only thing I find lacking is a section on which sounds are typically difficult for different language backgrounds.
