Vowels

Italian vowels are always articulated in a sharp, clear way, regardless of stress. In standard Italian a, i, u, are always pronounced the same way:
mano
dito
su

On the other hand, e and o in stressed syllables may represent either an open (è, ò) or a closed (é, ó) sound:
resto, rete
rosa, Roma

As a result, the vowel system displays seven different sounds: three front vowels (è, è, i), three back vowels (ò, ó, u), and one central vowel (a).

Front Vowels è
tè "tea"
é
perché "why, because"
i
vino "wine"
Back Vowels ò
però "but, on the contrary"
ó
sole "sun"
u
luna "moon"
Central Vowel a
mare "sea"

Please note that writing the accent is mandatory only on the last syllable, and just on some monosyllables, mostly with the function of disambiguating words pronounced in the same way but having different meanings:
tè: tea - te: you
là: there - la: the

Consonants
