O sound in Italian

The O sound in Italian is a vowel.

How to pronounce the O sound in Italian

O can be open or closed. When it’s unstressed, it’s always closed. When it’s stressed, it can be either open or closed.

Open any Italian dictionary and look up any word. In dictionaries…

  • open vowels are represented by a grave accent (`)
  • closed vowels are represented by an acute accent, (´).

Its IPA symbols are /ɔ/ (open o) and /o/ (closed o).

Although the quality of the vowel O in any given word is dictated by pronunciation rules, these rules are almost never followed by native speakers because pronunciation varies greatly from place to place in the country, so there’s really no “wrong” way to pronounce the E sound in Italian.

Only standard Italian, the accent that used on television, on the radio and in movie dubbing, actually follows the rules, but nobody speaks it in real life because the influence of regional accents is very strong.

Also, there’s no way people can misunderstand you if you pronounce an open O instead of a closed E. Homographs are very uncommon.

Length of the O sound

The O sound in Italian can be short or long.

It is long if it’s stressed and it’s at the end of the syllable, but not at the end of a word. For example…


Listen closely. The second “o” in perdono is long, since it’s stressed and is at the end of the syllable (do).

The stress is yet again on the second “o” vowel, but its length is short because the syllable ends with an -n (ton).
