Features

Features of the bilabial ejective fricative:

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 bilabial, which means it is articulated with both lips.
Its phonation is voiceless, which means it is produced without vibrations of the vocal cords.
It is an oral consonant, which means air is allowed to escape through the mouth only.
The airstream mechanism is ejective (glottalic egressive), which means the air is forced out by pumping the glottis upward.
