The voiceless labiodental approximant is a type of consonantal sound used in some spoken languages. The symbols in the International Phonetic Alphabet that represent this sound are ʋ̥ and , and the equivalent X-SAMPA symbols are P_0 (or v\_0) and f_o.

The voiceless labiodental approximant is the typical realization of /f/ in the Indian South African variety of English. As the voiced /v/ is also realized as an approximant ([ʋ]), it is also an example of a language contrasting voiceless and voiced labiodental approximants.[1]

Features

Features of the voiceless labiodental approximant:

  • 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.
  • Because the sound is not produced with airflow over the tongue, the centrallateral dichotomy does not apply.
