The voiceless labial–velar plosive or stop is a type of consonantal sound, used in some spoken languages.
The voiceless labial–velar plosive is found in Vietnamese and various languages in West and Central Africa.
[12] In the Banks Islands languages which have it, the phoneme /k͡pʷ/ is written ⟨q⟩ in local orthographies.
… the commonest double articulations consist of the simultaneous articulation of stops at two locations, most frequently labial-velar [kp] [gb], written [k͡p] [ɡ͡b] when the coarticulation has to be made explicit in transcription.
This particular type of double articulation is often called ‘labiovelar,’ a term which must be avoided in a strictly systematic phonetic taxonomy in which the first half of such a compound term refers to the lower articulator.Symbols to the right in a cell are voiced, to the left are voiceless.
