A series of graded packs, each level is divided into clearly differentiated sections which study the various fields of phonetics in Spanish (phonetic alphabet, vowels, consonants, accentuation, intonation, syllables...). Each section is carefully structured so that students learn, reinforce and improve their knowledge as they progress through the book. Numerous exercises are provided throughout which help to improve listening comprehension and pronunciation skills. Answers to the exercises are provided at the back of the book.
