Voiced labiodental affricate

A voiced labiodental affricate ([b̪͡v] in IPA) is a rare affricate consonant that is initiated as a voiced labiodental stop [b̪] and released as a voiced labiodental fricative [v].


Features of the voiced labiodental affricate:

  • Its manner of articulation is affricate, which means it is produced by first stopping the airflow entirely, then allowing air flow through a constricted channel at the place of articulation, causing turbulence.
  • There are two variants of the stop component:
    • bilabial, which means it is articulated with both lips. The affricate with this stop component is called bilabial-labiodental.
    • labiodental, which means it is articulated with the lower lip and the upper teeth.
  • The fricative component of this affricate is labiodental, articulated with the lower lip and the upper teeth.
  • Its phonation is voiced, which means the vocal cords vibrate during the articulation.
  • It is an oral consonant, which means air is allowed to escape through the mouth only.
  • It is a central consonant, which means it is produced by directing the airstream along the center of the tongue, rather than to the sides.
  • The airstream mechanism is pulmonic, which means it is articulated by pushing air solely with the lungs and diaphragm, as in most sounds.
