Sound

The close back rounded vowel, or high back rounded vowel, is a type of vowel sound, used in many spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is u, and the equivalent X-SAMPA symbol is u.

The IPA prefers terms "close" and "open" for vowels, and the name of the article follows this. However, a large number of linguists, perhaps a majority, prefer the terms "high" and "low".

In most languages this rounded vowel is pronounced with protruded lips ('endolabial'). However, in a few cases the lips are compressed ('exolabial').

Close back protruded vowel[edit]

In most languages, close back rounded vowels are pronounced with protruded lips.

  • Its vowel height is close, also known as high, which means the tongue is positioned as close as possible 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 as far back as possible in the mouth without creating a constriction that would be classified as a consonant. Note that unrounded back vowels tend to be centralized.
  • Its roundedness is protruded, which means that the corners of the lips are drawn together, and the inner surfaces exposed.

Occurrence[edit]

Note: Because back rounded vowels are assumed to have protrusion, and few descriptions cover the distinction, some of the following may actually have compression.

Close back compressed vowel[edit]

Close back compressed vowel
ɯᵝ

Some languages, such as Japanese About this sound listen  and Swedish, are found with a close back vowel that has a distinct type of rounding, called compressed or exolabial.[29] No language is known to contrast this with the more typical protruded (endolabial) close back vowel.

There is no dedicated diacritic for compression in the IPA. However, the compression of the lips can be shown with the letter β as ɯ͡β̞ (simultaneous [ɯ] and labial compression) or ɯᵝ ([ɯ] modified with labial compression). The spread-lip diacritic   ͍ may also be used with a rounded vowel letter as an ad hoc symbol.

Features[edit]

  • Its vowel height is close, which means the tongue is positioned as close as possible 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 as far back as possible in the mouth without creating a constriction that would be classified as a consonant.
  • Its roundedness is compressed, which means that the margins of the lips approach one another, so that the inner surfaces are not exposed.
