Features
Features of the voiced bilabial stop:
- 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 plosive.
- 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 exclusively allowed to escape through the mouth.
- Because the sound is not produced with airflow over the tongue, the central–lateral dichotomy does not apply.
- Its airstream mechanism is pulmonic, which means it is articulated by pushing air solely with the intercostal muscles and abdominal muscles, as in most sounds.
