Voiced bilabial fricative

The voiced bilabial fricative is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨β⟩, and the equivalent X-SAMPA symbol is B. The official symbol ⟨β⟩ is the Greek letter beta, though on the IPA chart the Latin beta ⟨ꞵ⟩ is used. The bilabial fricative is diachronically unstable and is likely to shift to [v]. The sound is not used in English dialects except for Chicano English, but it can be produced by approximating the normal English [v] between the lips.
