The open-mid central rounded vowel, or low-mid central rounded vowel, is a vowel sound, used in some spokenlanguages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɞ⟩, and the equivalent X-SAMPA symbol is 3\. The symbol is called closed reversed epsilon. It was added to the IPA in 1993; before that, this vowel was transcribed ⟨ɔ̈⟩.
Due to either typographic or design error, IPA charts were published with this vowel transcribed as a closed epsilon, ⟨ʚ⟩, and this graphic variant made its way into Unicode as U+029AʚLATIN SMALL LETTER CLOSED OPEN E. The form ⟨ɞ⟩ (U+025EɞLATIN SMALL LETTER CLOSED REVERSED OPEN E) is considered correct.
^McDonough, Ladefoged & George (1993). The authors gave a narrow transcription of [ɵ], though at the time the IPA had only this one symbol for a mid central rounded vowel, and it is clear from the discussion and formant charts that this vowel a centralized open-mid vowel.
