The voiced bilabial affricate ([b͡β] 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[edit]
Features of the 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 air is allowed to escape through the mouth only.
- It is a central consonant, which means it is produced by directing the airstream along the center of the tongue, rather than to the sides.
- The airstream mechanism is pulmonic, which means it is articulated by pushing air solely with the intercostal muscles and abdominal muscles, as in most sounds.
