The program goes where no American accent training tool has gone before, providing highly innovative instruction for both students and business people. The structure of the book has been reorganized, offering students a much more clear and direct sequence of lessons and a path to better understanding. Supplementary materials include detailed nationality guides for 11 languages (Chinese, Japanese, Indian, Spanish, French, German, Russian, Korean, Arabic, the U.S. Southern accent, and African languages). More valuable features include access to a comprehensive website, and referral to a qualified telephone analyst for an individual diagnostic speech analysis.
