This book is most useful for learning or teaching English as a second or foreign language (ESL/EFL). At first, I was scared that the audio CDs would contain audio tracks with an acute American English twang but the CDs ended up being very clear in pronunciation and these improved my students' aural skills nonetheless. Realistically, this is useful for improving aural/listening skills for the TOEIC/TOEFL, English exams for the baccalauréat and overall speech improvement. This is highly recommended for EU/foreign high school ESL/EFL students, adult learners and university oral English exams (specifically for speech or listening tests/phonology tests). ( )
