Voiced linguolabial fricative
ð̼
β̺

The linguolabial fricative is a type of consonantal sound used in some spoken languages. The symbol in the International Phonetic Alphabet that represents it is ð̼ or β̺.

Features[edit]

Features:

  • 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 linguolabial, which means it is articulated with the tongue against the upper lip.
  • Its phonation is voiced, which means the vocal cords vibrate during the articulation. However, in some languages (like Swiss German) it can just mean that this consonant is pronounced shorter and weaker than its voiceless counterpart, while its voicedness or lack thereof is not relevant. In such cases it's more accurate to call such sounds lenis or lax.
  • It is an oral consonant, which means air is allowed to escape through the mouth only.
  • The airstream mechanism is pulmonic, which means it is articulated by pushing air solely with the lungs and diaphragm, as in most sounds.
