The close central rounded vowel is the vocalic equivalent of the rare labialized post-palatal approximant [ẅ].
In most languages this rounded vowel is pronounced with protruded lips (endolabial). However, in a few cases the lips are compressed (exolabial).
Some languages feature the near-close central rounded vowel (ⓘ), which is slightly lower. It is most often transcribed in IPA with ⟨ʉ̞⟩, ⟨ʊ̈⟩ and ⟨ʊ̟⟩, but ⟨ɵ̝⟩ is also a possible transcription. The symbol ⟨ᵿ⟩, a conflation of ⟨ʊ⟩ and ⟨ʉ⟩, is used as an unofficial extension of the IPA to represent this sound by a number of publications, such as Accents of English by John C. Wells. In the third edition of the Oxford English Dictionary, ⟨ᵿ⟩ represents free variation between /ʊ/ and /ə/.
