Query: Excellent work

The author is very passionate, enthusiastic and experienced. Language is practice and this is a good foundation that can help you (8CD's of pure sounds size does matter) it helps your ears to identify sounds and hopefully to look for them while in general life situations, watching TV or listening to radio so you can sincerely succeed in your efforts to reduce accent. Now that you have the right ear you can record and listen to yourself.Surely it would help in both TOEFL and TSE (Test of Spoken English).I will certainly wait for her new publications, hopefully there will be part II and may be III with the author's simplicity and technology sophistication.
