e is sometimes like e in “set” and sometimes like a in “spade”
i as in “macaroni”
i before an unstressed vowel is like English y
o is sometimes like o in “so” and sometimes like o in “gore”
u as in “tune”
u before an unstressed vowel is like English w
Otherwise, when two or more vowels are together, pronounce the sounds of each vowel separately.
Consonants
Most of the consonants are pronounced as they are in American English with these exceptions:
c before a, o and u like English k
c before i and e like ch in “cheese”
ch like English “k”
g before a, o and u as in “go”
g before i and e as in “gem”
gh like g in “go”
gli like ll in “million”
gn close to ny in “canyon”
h is always silent
r should be trilled
s is sometimes like English s and sometimes like English z
sc before a, o and u like sk in “skin”
sc before i and e like sh in “shin”
sch like sk in “skin”
z is sometimes like ts in “bets” and sometimes like ds “beds”
When ci, gi, and sci are followed by a, o, or u, unless the accent falls on the i, the i is not pronounced. The letter i merely indicates that c, g and sc are pronounced, respectively, like the English ch, g in “gem,” and sh.
Emphasis
Emphasis is somewhat random as in English but usually falls on the second to the last syllable.
Italian is a member of the Italo-Dalmatian group of languages, which is part of the Italo-Western grouping of the Romance languages, which are a subgroup of the Italic branch of Indo-European.
Italian is the official language of Italy and San Marino, and is an official language in Ticino and Grigioni cantons of Switzerland.
Italian has few diphthongs, and so most unfamiliar diphthongs heard in foreign words (in particular, those with a first vowel that is not "i" or "u", or a first vowel that is stressed), will be assimilated as the corresponding dieresis (i.e., the vowel sounds will be pronounced separately: "strive" and "hive" will rhyme with "naïve").
