This book is aimed at helping Spanish speakers to overcome their communication problems in English by introducing the most relevant issues of English pronunciation and comparing them with those of Spanish pronunciation. It covers not only vowels and consonants but also other aspects such as stress, rhythm, intonation, words in company, combinations of sounds and accent placement. The book is accompanied by a CD-ROM which contains more than 2000 audio entries and interactive ear-training exercises with inmediate feedback. The audio material includes voice recordings of four native English speakers. "Let's speak and understand English once and for all!"
