Dentolabial consonant

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.
