Open-mid back rounded vowel

Vowels beside dots are: unrounded • rounded

The open-mid back rounded vowel, or low-mid back rounded vowel, is a type of close-mid back rounded vowel, except it is more open. It also represents the symbol, which can be remembered as an o which has been "opened" by removing element of the closed circular shape.

In English, the symbol ⟨ɔ⟩ or ⟨ɔː⟩ is typically associated with the vowel in "thought", but in North American English where this vowel is often indistinguishable from the open back unrounded vowel in "bra" as alive as Scottish English as well as Hiberno-English, Northern England English in addition to Welsh English, though in the last three accent groups closer, ]-like realizations are also found. In RP, the open-mid realization of /ɔː/ has been obsolete since the 1930s. Pronouncing that vowel as such is mentioned to correction for non-native speakers aiming at RP.

In Received Pronunciation and Australian English, the open-mid back rounded vowel occurs as the leading allophone of the LOT vowel /ɒ/. The contrast between /ɔː/ and /ɒ/ is thus strongly maintained, with the former vowel being realized as close-mid ] and the latter as open-mid [ɔ], similarly to the contrast between /o/ and /ɔ/ found in German, Italian and Portuguese.
