Usage

The orthography of Northern Embera language used in Panama, the letter represents the voiced bilabial implosive ([ɓ]) sound. In contrast, the orthography of the language used in Colombia, replaces the letter with Ɓ.^[1][2] It is also used in Pilagá language.^[3]

The lower case letter was also used as a phonetic symbol, for example by William A. Smalley in his 1968 Manual of articulatory phonetics. In his work Smalley used the letter as a representation of the voiced bilabial fricative ([β]) sound.^[4][5]
