Dalton and Seidlhofer have written a good pronunciation introduction for those wishing to tackle this complex and often perplexing language system. The book is mostly theoretical, but never loses sight of the practical side of life.
"Pronunciation" covers aspects of pronunciation that include "the nature of speech sounds", intonation, connected speech, stress, teaching pronunication, concentrating on intonation, concentrating on connected speech and other chapters. Splashed throughout are reader tasks that highlight the points being made in very practical ways. For example, rather than just telling the read what happens in connected speech, they will give you a couple of example utterances to try, having a couple of questions for you to think about, and then deal with the point of it all.
Although not as "sample lesson" orientated as Gerald Kelly's How To Teach Pronunciation (Book with Audio CD), this is definitely a valuable resource to have around. It is exceptionally thorough and gives the reader an excellent overview of the topic. There are plenty of tasks to use in the class when you want to explore this system, but as said, they are not "sample lessons", per se. A very good book by any standard, I think.
