Legend: unrounded • rounded

The close back unrounded vowel, or high back 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 ⟨ɯ⟩. Typographically, it is a turned letter ⟨m⟩.

The close back unrounded vowel can in many cases be considered the vocalic equivalent of the voiced velar approximant [ɰ].

Features

Its vowel height is close, also known as high, which means the tongue is positioned close to the roof of the mouth without creating a constriction that would be classified as a consonant.
Its vowel backness is back, which means the tongue is positioned back in the mouth without creating a constriction that would be classified as a consonant. Unrounded back vowels tend to be centralized, which means that often they are in fact near-back.
It is unrounded, which means that the lips are not rounded.
