Sound sample (help·info)

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 symbol β is the Greek letter beta. This symbol is also sometimes used to represent the bilabial approximant, though that is more clearly written with the lowering diacritic, β̞. In the English language, this sound is not used, but is made by making the normal "v" sound without fully closing the lips or without touching the top teeth to the lower lip.
