Most Italian consonant sound the same as in English. However, there are a few spelling peculiarities you should take notice of:
c before an e or an i is always pronounced soft
ch is always pronounced hard, as in the letter k
ca, co, and cu are always pronounced hard
For example: c soft in pace (peace) or cielo (sky), hard in caldo (hot), coda (tale), cucchiaio (tablespoon), chiesa (church), buche (holes).
g before an e or an i is always pronounced soft
gh is always pronounced hard (and it can only be followed by e or i)
ga, go, and gu are always pronounced hard
When g comes before a, o, and u and before consonants it sounds like the g in go. When g comes before e and i it sounds soft like the g in gelato.
For example: g is soft in gelato (icecream), giostra (carousel); it’s hard in garda, pagoda, gusto (taste), ghiro (dormouse), ghetto.
sc like pesce, sciopero, and scempio is soft
Sch like scherzo, schettini, bruschetta is hard (like k)
Two other tricky sound combinations are gl and gn.
gn like gnomi is pronounced soft, as in gnocchi (where the g is soft but the ch is hard)
gl : maglia (sweater), aglio (garlic).
Another important difference is with double consonants. In English, it usually makes no difference but in Italian it does. A double consonant is pronounced over a longer period of time than a single consonant. You already know one example: the pronunciation of pizza.
For some consonants in particular: t, d, c, g, p and b there is no way to lengthen the consonant sound. Instead you stretch the holding period before you release the consonant – for instance there is a difference in Italian between fato (fate) and fatto (fact).
Some more examples:
eco (echo) and ecco (here is)
ala (wing) and alla (to the)
nono (ninth) and nonno (grandfather)
poso (I pose) and posso (I can)
