The close-mid central unrounded vowel, or high-mid central unrounded vowel,[1] is a type of vowel sound used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɘ⟩. This is a mirrored letter e and should not be confused with the schwa ⟨ə⟩, which is a turned e. It was added to the IPA in 1993; before that, this vowel was transcribed ⟨ë⟩. Certain older sources[2] transcribe this vowel ⟨ɤ̈⟩.
^ abJassem (2003:105) The source transcribes this sound with the symbol ⟨ɨ⟩ but one can see from the vowel chart at pag. 105 that the Polish sound is closer to [ɘ] than to [ɨ].
