Mid back unrounded vowel

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