Voiced bilabial affricate
Consonantal sound
From Wikipedia, the free encyclopedia
A voiced bilabial affricate ([bÍβ] in IPA) is a rare affricate consonant that is initiated as a bilabial stop [b] and released as a voiced bilabial fricative [β]. It has not been reported to occur phonemically in any language.
Features
Features of a voiced bilabial 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.
- Its place of articulation is bilabial, which means it is articulated with both lips.
- Its phonation is voiced, which means the vocal cords vibrate during the articulation.
- It is an oral consonant, which means that air is not allowed to escape through the nose.
- Because the sound is not produced with airflow over the tongue, the medianâlateral dichotomy does not apply.
- Its airstream mechanism is pulmonic, which means it is articulated by pushing air only with the intercostal muscles and abdominal muscles, as in most sounds.
