In phonetics, describes labiovelar the articulation of a sound at the lips (Latin labium ) and the soft palate ( velum Latin ). In this case, " labiovelar " either represent a velar consonant or a labialized at two places at the same articulation labial- velar consonants spoken.
As labialisierte velars [k ʷ ], [ g ʷ ], [ x ʷ ], [ ɣ ʷ ] is denoted by lip rounding spoken velars [k ], [ g], [x ], [ ɣ ] etc.
The most common labialisierte velar is voiced velar approximant of labialisierte [ w] (as in Engl. Witch [ wɪtʃ ] " witch "). Some varieties of English hereof distinguish the unvoiced fricative labiovelaren [ ʍ ] as in which [ ʍɪtʃ ] " which ".
The Indo-European proto-language had a number labialisierter velars, namely [k ʷ ], [ g ʷ ] (or after Glottaltheorie [k ʷ ˀ ] ), and [g ʷ ʰ ]. However, these are only in the western ( Germanic and Celtic languages) and southern propagation region detectable, namely the Italian, Greek, Anatolian, and to a lesser extent even in the latter closely related to Tocharian languages). In Greek and Celtic they have partially developed into pure labials.
In the other languages ( with palatalization, the so-called Satemsprachen ) they fell together by Delabialisierung with the simple velars.
Labial - velar
The labial- velar consonants are simultaneously speaking on the lips (Latin labium ) and the soft palate ( velum Latin ). This is not a consonant cluster but a simple sound which is spoken in two places at the same articulation. These sounds occur in languages of West and Central Africa and New Guinea, and end of the word in Vietnamese. Examples of labial- velar consonants are:
- [KP ] Logba ò - kpàyɔ [ ò - k͡pàyɔ ] "God"
- [GB ] Ewe Ewegbe [ ɛβɛg͡be ] ( proper name of the language)
- [ NM ] Vietnamese cung [ KUNM ] "sector"
