Close-mid central rounded vowel

The close-mid central protruded vowel is typically transcribed in IPA simply as ⟨ɵ⟩, and that is the convention used in this article. As there is no dedicated diacritic for protrusion in the IPA, symbol for the close central rounded vowel with an old diacritic for labialization, ⟨  ̫⟩, can be used as an ad hoc symbol ⟨ɵ̫⟩ for the close central protruded vowel. Another possible transcription is ⟨ɵʷ⟩ or ⟨ɘʷ⟩ (a close central vowel modified by endolabialization), but this could be misread as a diphthong.

Occurrence

Because central rounded vowels are assumed to have protrusion, and few descriptions cover the distinction, some of the following may actually have compression.

As there is no official diacritic for compression in the IPA, the centering diacritic is used with the front rounded vowel [ø], which is normally compressed. Other possible transcriptions are ⟨ɘ͡β̞⟩ (simultaneous [ɘ] and labial compression) and ⟨ɘᵝ⟩ ([ɘ] modified with labial compression).
