Voiced bilabial implosive
A voiced bilabial implosive is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɓ⟩, and the equivalent X-SAMPA symbol is
|Voiced bilabial implosive|
Features of the voiced bilabial implosive:
- Its manner of articulation is occlusive, which means it is produced by obstructing airflow in the vocal tract. Since the consonant is also oral, with no nasal outlet, the airflow is blocked entirely, and the consonant is a stop.
- 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.
- Because the sound is not produced with airflow over the tongue, the central–lateral dichotomy does not apply.
- The airstream mechanism is implosive (glottalic ingressive), which means it is produced by pulling air in by pumping the glottis downward. Since it is voiced, the glottis is not completely closed, but allows a pulmonic airstream to escape through it.
