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]
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.
