The book and CD were right on target for what I needed for my role.The resonance, the vowel changes, the HARD consanants and the lilt andrhythum were excellent lessons for me. This is only the second role whichhas required an accent (the other being Texan), and I would not even have come close without this aid.I ordered it on a Wednesday, and received it by the next MondayThe supply vendor was excellent.
