3. Vowels, consonants and varieties

This issue is focused on the two kinds of Spanish sounds: vowels and consonants.

The vowels are the five sounds (a, e, i, o, u) that are pronounced with an open mouth without obstruction of the tongue, lips or teeth; while with the consonants, on the other hand, the air encounters some obstacle; they are the rest of the letters of the alphabet, excluding the vowels referred to above.

Finally, the book addresses the linguistic varieties since Spanish, by its geographical extension and influence from other languages, forms a rich melting pot of speech varieties.
