(Redirected from Labial-velar)
'Labial-velar consonants' are doubly articulated at the
velum and the
lips. They are sometimes called "
labiovelar consonants", a term which can also refer to
labialized velars, such as the
approximant .
Truly doubly articulated labial-velars occur as
plosives and
nasal stops in the majority of languages in West and Central Africa, and are relatively common in the eastern end of New Guinea. They include . The
Yélî Dnye language of
Rossel Island,
Papua New Guinea, has both labial-velars and
labial-alveolar consonants. Labial velar unvoiced plosives and nasals also occur in
Vietnamese, albeit only at the end of words.
To pronounce these, try saying , but close your lips as you would for . Then release just as you would do to produce these sounds. Note that while 90% of the occlusion overlaps, the onset of the velar occurs slightly before that of the labial, and the release of the labial occurs slightly after that of the velar, so that the preceding vowel sounds like it's followed by a velar, while the following vowel sounds like it's following a labial. Thus the order of the symbols in and is motivated by the phonetic details of these sounds.
These sounds are clearly single consonants rather than
consonant clusters. The
Eggon language, for example, contrasts these possibilities, with /bg/ and /gb/ both distinct from . Ignoring tone, we have:
| Single consonant | Two-consonant sequence |
|---|
| ''to pound'' | | ''to dig'' |
| ''a dog'' | | ''to beat, to kill'' |
| ''a room'' | | ''a stomach'' |
| ''to break'' | | ''to grind'' |
| ''to die'' | | ''to kneel'' |
| ''to arrive'' | | ''to divide'' |
For transcribing these sounds, occasionally ligatures will be seen instead of digraphs with a tie bar:

Note that although such symbols are readily understood, they are not sanctioned by the IPA, and have no
Unicode values. They can, however, be specified as the way an
OpenType font displays ''gb'' and ''kp'' digraphs.
Labial-velar plosives also occur as
ejective and
implosive (the tie bar has been removed for legibility). There may be labial-velar approximants in languages like
Japanese; see
labiovelar consonant. The only other labial-velar consonants are the velar
bilabial clicks.
