Voiceless labiodental affricate
|Voiceless labiodental affricate|
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.
The sound occurs occasionally in English, in words where one syllable ends with "p" and the next starts with "f", like in "helpful" or "stepfather".
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:
- 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.
