Labial-velar consonants are doubly articulated at the Velum and the Lip s. They are sometimes called " Labiovelar Consonant s", a term which can also refer to Labialized velars, such as the Approximant . Truly doubly articulated labial-velars occur as Plosive s and Nasal Stop s in the majority of languages in West and Central Africa, and are relatively common in the eastern end of New Guinea. They include . The Yelî Dnye Language of Rossel Island , Papua New Guinea , has both labial-velars and Labial-alveolar Consonant s. 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 Cluster s. The Eggon Language , for example, contrasts these possbilities, with /bg/ and /gb/ both distinct from . Ignoring tone, we have: 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 Click s. SEE ALSO |
