A voiceless labiodental affricate ([p̪͡f] in IPA) is a rare affricate consonant that is initiated as a labiodental stop [p̪] and released as a voiceless labiodental fricative [f].

The XiNkuna dialect of Tsonga has this affricate, as in [tiɱp̪͡fuβu] "hippopotamuses" and aspirated [ɱp̪͡fʰuka] "distance" (compare [ɱfutsu] "tortoise", which shows that the stop is not epenthetic), as well as a voiced labiodental affricate, [b̪͡v], as in [ʃileb̪͡vu] "chin". There is no voiceless labiodental fricative [f] in this dialect of Tsonga, only a voiceless bilabial fricative, as in [ɸu] "finished". (Among voiced fricatives, both [β] and [v] occur, however.)

German has a similar sound /p͡f/ in Pfeffer /ˈp͡fɛfər/ ('pepper') and Apfel /ˈap͡fəl/ ('apple'). Phonotactically, this sound does not occur after long vowels, diphthongs or /l/. It differs from a true labiodental affricate in that it starts out bilabial but then the lower lip retracts slightly for the frication.

Features

Features of the voiceless labiodental 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.
  • There are two variants of the stop component:
    • bilabial, which means it is articulated with both lips. The affricate with this stop component is called bilabial-labiodental.
    • labiodental, which means it is articulated with the lower lip and the upper teeth.
  • The fricative component of this affricate is labiodental, articulated with the lower lip and the upper teeth.
  • 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.
  • The airstream mechanism is pulmonic, which means it is articulated by pushing air solely with the lungs and diaphragm, as in most sounds.
