Labioalveolar consonant

Not to be confused with Labial–alveolar consonant.

Labioalveolar consonants are articulated with the lower lip against the alveolar ridge. They are only found in disordered speech, typically occurring in speakers with excessive overbite when articulating labial consonants.^[1] In the extIPA, they are represented with the alveolar diacritic ⟨◌͇⟩ on the corresponding labial. To avoid descenders, it may be placed above instead: ⟨◌᫨⟩.^[2][3]
