Teaching American English Pronunciation – Oxford Handbooks for Language Teachers [EPUB ebook] 

As an ESL teacher, have you looked at the phonetics textbooks on the market and decided that they don’t directly address your needs? Unlike pronunciation books aimed at students of linguistics or at learners of English, Teaching American English Pronunciation has been written specifically for ESL teachers. It doesn’t only give academic descriptions, but also helps you to improve your students’ pronunciation effectively.
