Abilabial ejective fricative is a rare type ofconsonantal sound. The symbol in theInternational Phonetic Alphabet that represents this sound is ⟨ɸʼ⟩.

Features of a bilabial ejective fricative:

• Itsmanner of articulation isfricative, which means it is produced by constricting air flow through a narrow channel at the place of articulation, causingturbulence.
• Itsplace of articulation isbilabial, which means it is articulated with bothlips.
• Itsphonation is voiceless, which means it is produced without vibrations of the vocal cords.
• It is anoral consonant, which means that air is not allowed to escape through the nose.
• Because the sound is not produced with airflow over the tongue, themedian–lateral dichotomy does not apply.
• Theairstream mechanism isejective (glottalic egressive), which means the air is forced out by pumping theglottis upward.
