Avoiceless bilabial affricate ([p͡ɸ] inIPA) is a rareaffricate consonant that is initiated as abilabial stop[p] and released as avoiceless bilabial fricative[ɸ]. It has not been reported to occurphonemically in any language.

Features of a voiceless bilabial affricate:

Itsmanner of articulation isaffricate, 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.
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. In some languages the vocal cords are actively separated, so it is always voiceless; in others the cords are lax, so that it may take on the voicing of adjacent sounds.
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, thecentral–lateral dichotomy does not apply.
Itsairstream mechanism ispulmonic, which means it is articulated by pushing air only with theintercostal muscles andabdominal muscles, as in most sounds.
