Close back rounded vowel
Template:Short description Template:Redirect Template:Infobox IPA Template:IPA vowels
The close back rounded vowel, or high back rounded vowel,<ref>Template:Vowel terminology</ref> is a type of vowel sound used in many spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is Template:Angbr IPA.
In most languages, this rounded vowel is pronounced with protruded lips ('endolabial'). However, in a few cases the lips are compressed ('exolabial').
{{#invoke:IPA|main}} alternates with labio-velar approximant {{#invoke:IPA|main}} in certain languages, such as French, and in the diphthongs of some languages, {{#invoke:IPA|main}} with the non-syllabic diacritic and {{#invoke:IPA|main}} are used in different transcription systems to represent the same sound.
Close back protruded vowel
The close back protruded vowel is the most common variant of the close back rounded vowel. It is typically transcribed in IPA simply as Template:Angbr IPA (the convention used in this article). As there is no dedicated IPA diacritic for protrusion, the symbol for the close back rounded vowel with an old diacritic for labialization, Template:Angbr IPA, can be used as an ad hoc symbol Template:Angbr IPA. Another possible transcription is Template:Angbr IPA or Template:Angbr IPA (a close back vowel modified by endolabialization), but that could be misread as a diphthong.

Occurrence
Close back compressed vowel
Template:Infobox IPA Some languages, such as Japanese and Swedish, have a close back vowel that has a distinct type of rounding, called compressed or exolabial.Template:Sfnp Only Shanghainese is known to contrast it with the more typical protruded (endolabial) close back vowel, but the height of both vowels varies from close to close-mid.Template:Sfnp
As there are no diacritics in the IPA to distinguish protruded and compressed rounding, an old diacritic for labialization, Template:Angbr IPA (the opposite of Template:Angbr IPA), will be used here as an ad hoc symbol for compressed back vowels. It was only added to Unicode in 2025, however, and it may take some time for font support to catch up. Compression of the lips can be shown with the letter Template:IPAalink as Template:Angbr IPA (simultaneous {{#invoke:IPA|main}} and labial compression) or Template:Angbr IPA ({{#invoke:IPA|main}} modified with labial compression), though that can suggest that the vowel is a diphthong (as indeed it is in Swedish).
