American Accent Training by Ann Cook and published by Barron's provides a self study course that is sure to improve any advanced level student's pronunciation. This course includes a course book and five audio CDs. The book includes all the exercises, quiz material and reference material that are found on the audio CDs. In this way, learners follow their course by reading, listening and repeating materials that are oral in nature, but also provided in print.
The course takes what is termed a 'pure-sound' approach to learning standard American pronunciation. To put it simply, this course focuses on learning the 'music' of English as it spoken in the USA. The stress-timed nature of English is put emphasized with correct intonation, stress and liaison used to develop natural sounding speech patterns. These speech patterns are then combined with specific vowel and consonant patterns in connected speech in exercises which lead to improved, natural American sounding, pronunciation.
