Labiodental consonant

Summary
In phonetics, labiodentals are consonants articulated with the lower lip and the upper teeth. The labiodental consonants identified by the International Phonetic Alphabet are: The IPA chart shades out labiodental lateral consonants. This is sometimes read as indicating that such sounds are not possible. In fact, the fricatives [f] and [v] often have lateral airflow, but no language makes a distinction for centrality, and the allophony is not noticeable. The IPA symbol ɧ refers to a sound occurring in Swedish, officially described as similar to the velar fricative [x], but one dialectal variant is a rounded, velarized labiodental, less ambiguously rendered as [fɣw]. The labiodental click is an allophonic variant of the (bi)labial click. The only common labiodental sounds to occur phonemically are the fricatives and the approximant. The labiodental flap occurs phonemically in over a dozen languages, but it is restricted geographically to central and southeastern Africa (Olson & Hajek 2003). With most other manners of articulation, the norm are bilabial consonants (which together with labiodentals, form the class of labial consonants). [ɱ] is quite common, but in all or nearly all languages in which it occurs, it occurs only as an allophone of /m/ before labiodental consonants such as /v/ and /f/. It has been reported to occur phonemically in a dialect of Teke, but similar claims in the past have proven spurious. The XiNkuna dialect of Tsonga features a pair of affricates as phonemes. In some other languages, such as Xhosa, affricates may occur as allophones of the fricatives. These differ from the German voiceless labiodental affricate , which commences with a bilabial p. All these affricates are rare sounds. The stops are not confirmed to exist as separate phonemes in any language. They are sometimes written as ȹ ȸ (qp and db ligatures). They may also be found in children's speech or as speech impediments. Dentolabial consonants are the articulatory opposite of labiodentals: They are pronounced by contacting lower teeth against the upper lip.
