Labial–alveolar consonant

Labial–alveolar consonants are doubly articulated consonants that are co-articulated at the lips and the front part of the tongue against the alveolar ridge or the alveolar ridge and the teeth. They are only attested in Yele, an unclassified language of Rossel Island, Papua New Guinea.

Types
Several labial–alveolar consonants are attested in Yele, where the alveolar contact is more precisely denti-alveolar: a voiceless plosive, a nasal , and prenasalized (also analyzed as  but phonetically voiced), of which  and  may also occur palatalized.
