As there is no dedicated diacritic for protrusion in the IPA, the symbol for the close-mid back rounded vowel with an old diacritic for labialization, ⟨  ̫⟩, can be used as an ad hoc symbol ⟨o̫⟩ for the close-mid back protruded vowel. Another possible transcription is ⟨oʷ⟩ or ⟨ɤʷ⟩ a close-mid back vowel modified by endolabialization, but this could be misread as a diphthong.

For the close-mid near-back protruded vowel that is normally transcribed with the symbol ⟨ʊ⟩, see near-close back protruded vowel. whether the usual symbol is ⟨o⟩, the vowel is described here.
