This book helps teachers of English to provide speakers of other languages the basic information and tools they need to help their students master the phonological system of English. The elements emphasized are those that contribute to more effective classroom practices. More specifically, teachers of English as a second or foreign language will find this book of value to them in a number of ways: as a tool to sharpen their own ears to hear some sounds that they might not have heard or been aware of before; as a tool to help them pronounce English sounds more intelligibly and accurately; as a resource on the phonological system of English; as a contributing factor to more effective linguistic pedagogy in the classroom; and as a way of developing a more wholesome attitude towards language, all aspects of language teaching and learning in general, and toward pronunciation in particular. A glossary of technical terms and a list of study questions are included.
