A voiceless bilabial affricate ([p͡ɸ] in IPA) is a rare affricate consonant that is initiated as a bilabial stop [p] and released as a voiceless bilabial fricative [ɸ]. It has not been reported to occur phonemically in any language.
Features of the voiceless bilabial affricate:
- Its manner of articulation is affricate, 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.
- Its phonation 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 an oral consonant, which means air is allowed to escape through the mouth only.
- It is a central consonant, which means it is produced by directing the airstream along the center of the tongue, rather than to the sides.
