produced with two simultaneous articulators: with the lips ('labial'; a , , or sound), and with the tongue (at the teeth or gums, a 'dental' or 'alveolar' , or sound, or further back, a 'post-alveolar' or 'retroflex' , or sound). Several languages have been claimed to have such sounds, such as Margi and Bura in Nigeria. However, most researchers interpret them as having sequences of labial and coronal consonants, a rather common occurrence in Africa. The

Although the double stop articulation may be more common, they are generally considered to be essentially labialized alveolars because the labial contact is light, and moreover the contact is between the inner surfaces of the lips, which are protruded as they are for This is quite different from the normal contact for in these languages. The labial contact may also be realized as a trill. Compare the following minimal sets in Ubykh: Some speakers of
