Voiced labiodental approximant

The voiced labiodental approximant is a type of consonantal sound, used in some spoken languages. It is something between an English /w/ and /v/, pronounced with the teeth and lips held in the position used to articulate the letter V. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ʋ⟩, a letter v with a leftward hook protruding from the upper right of the letter, and the equivalent X-SAMPA symbol is P or v\. With an advanced diacritic, ⟨ʋ̟⟩, this letter also indicates a bilabial approximant, though the diacritic is frequently omitted because no contrast is likely.^{[failed verification]}

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

Features of the voiced labiodental approximant:

• Its manner of articulation is approximant, which means it is produced by narrowing the vocal tract at the place of articulation, but not enough to produce a turbulent airstream.
• Its place of articulation is labiodental, which means it is articulated with the lower lip and the upper teeth.
• Its phonation is voiced, which means the vocal cords vibrate during the articulation.
• 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 central–lateral dichotomy does not apply.
• Its airstream mechanism is pulmonic, which means it is articulated by pushing air solely with the intercostal muscles and abdominal muscles, as in most sounds.
