Mid back unrounded vowel

The mid back unrounded vowel is a type of vowel sound, used in some spoken languages. While there is no dedicated symbol in the International Phonetic Alphabet that represents the "exact" mid back unrounded vowel between close-mid and open-mid  (since no language is known to distinguish all three), $\langle\rangle$ is normally used. If precision is desired, diacritics can be used, such as $\langle\rangle$ or $\langle\rangle$.
