The sound is similar to voiced alveolar fricative /z/ in that it is familiar to most European speakers^{[citation needed]} but is a fairly uncommon sound cross-linguistically, occurring in approximately 21.1% of languages.^[1] Moreover, most languages that have /z/ also have /v/ and similarly to /z/, the overwhelming majority of languages with [v] are languages of Europe, Africa, or Western Asia, although the similar labiodental approximant /ʋ/ is also common in India. The presence of [v] and absence of [w], is a very distinctive areal feature of European languages and those of adjacent areas of Siberia and Central Asia.^{[citation needed]} Speakers of East Asian languages that lack this sound may pronounce it as [b] (Korean and Japanese), or [f]/[w] (Cantonese and Mandarin), and thus be unable to distinguish between a number of English minimal pairs.^{[citation needed]}

In certain languages, such as Danish,^[2] Faroese,^[3] Icelandic or Norwegian^[4] the voiced labiodental fricative is in a free variation with the labiodental approximant.

Features of the voiced labiodental fricative:

• Its manner of articulation is fricative, which means it is produced by constricting air flow through a narrow channel at the place of articulation, causing turbulence.
• 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.
• The airstream mechanism is pulmonic, which means it is articulated by pushing air solely with the intercostal muscles and abdominal muscles, as in most sounds.
