FeaturesEdit

Features of the voiceless bilabial fricative:

  • Its manner of articulation is fricative, which means it is produced by constricting air flow through a narrow channel at the place of articulation, causing turbulence.
  • Its place of articulation is bilabial, which means it is articulated with both lips.
  • Its phonation is voiceless, which means it is produced without vibrations of the vocal cords. In some languages the vocal cords are actively separated, so it is always voiceless; in others the cords are lax, so that it may take on the voicing of adjacent sounds.
  • It is an oral consonant, which means air is allowed to escape through the mouth only.
  • Because the sound is not produced with airflow over the tongue, the centrallateral dichotomy does not apply.
  • The airstream mechanism is pulmonic, which means it is articulated by pushing air solely with the intercostal muscles and diaphragm, as in most sounds.
