Voiced linguolabial fricative

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

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.

• 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.
