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.

Features of the voiced bilabial fricative:

In speech there are different ways of producing a consonant. ... Fricatives (or spirants) are consonants produced by forcing air through a narrow channel made by placing two articulators close together. ... Turbulent flow around an obstacle; the flow further away is laminar Laminar and turbulent water flow over the hull of a submarine Turbulence in the tip vortex from an airplane wing In fluid dynamics, turbulence or turbulent flow is a flow regime characterized by low momentum diffusion, high momentum convection...

In English

This sound does not exist in English. An English speaker can make this sound by pronouncing a b, with the lips touching only lightly, so that they 'buzz' as they do for a v. The English language is a West Germanic language that originates in England. ...

In other languages


In some dialects of European Spanish, v is pronounced [β]. In other European dialects, as well as most American Spanish, both b and v are approximants [β̞] between vowels, though they are often transcribed as if they were fricatives.

The voiced bilabial fricative is a type of consonantal sound, used in some spoken languages.
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 phonation type is voiced, which means the vocal cords are vibrating during the articulation.
