By 1500 BC, the Phoenician alphabet's letter had a linear form that served as the beth.

Typography

The modern lowercase letter b derives from later Roman times, when scribes began omitting the upper loop of the capital.

Usage

In English and most other languages that use the Latin alphabet, the letter b denotes the voiced bilabial plosive (IPA /b/), as in bib. In English it is sometimes "silent", as in debt or comb (however the 'b' in 'comb' was actually pronounced at one time). In Estonian, Icelandic, and in Chinese transcription, B is not voiced, but is still contrasted to P, which is geminated /pp/ in Estonian and aspirated /pʰ/ in Chinese and Icelandic.

In the International Phonetic Alphabet and X-SAMPA, letter /b/ denotes the voiced bilabial plosive. Variants of the letter b denote related bilabial consonants, like the voiced bilabial implosive and the bilabial trill. In X-SAMPA, capital B denotes the voiced bilabial fricative.
