Close-mid central unrounded vowel

The close-mid central unrounded vowel, or high-mid central unrounded vowel, is a type of vowel sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is $\langle\rangle$. This is a reversed letter e, and should not be confused with the schwa $\langle\rangle$, which is a turned e. It was added to the IPA in 1993; before that, this vowel was transcribed $\langle\rangle$ (Latin small letter e with umlaut, not Cyrillic small letter yo). This letter may be used with a lowering diacritic $\langle\rangle$, to denote the mid central unrounded vowel.
