Bilabial Stop

In phonetics and phonology, a bilabial stop is a type of consonantal sound, made with both lips (hence bilabial), held tightly enough to block the passage of air (hence a stop consonant). The most common sounds are the stops and, as in English pit and bit, and the voiced nasal . More generally, several kinds are distinguished:

  • , voiceless bilabial stop
  • , voiced bilabial stop
  • , voiced bilabial nasal
  • , voiceless bilabial nasal
  • , voiced bilabial implosive
  • , bilabial ejective (rare)
  • or, voiceless bilabial implosive (very rare)

Famous quotes containing the word stop:

    “Roger Thornhill: Tell me, how does a girl like you get to be a girl like you?
    Eve Kendall: Lucky I guess.
    Roger Thornhill: No, not lucky. Naughty, wicked, up to no good. Ever kill anyone? Because I bet you could tease a man to death without half trying. So stop trying.”
    —Ernest Lehman (b.1920)
