Voiced bilabial plosive to Voiceless velar plosive

A direct, one-step historical phonetic shift from a voiced bilabial plosive [b] to a voiceless velar plosive [k] is generally considered phonetically uncommon due to the significant changes in both place of articulation and voicing. However, such a transformation is attested as a regular sound change in the history of Berawan, an Austronesian language. This shift, primarily occurring in intervocalic positions, is understood to have proceeded through an intermediate stage, involving both a change in the place of articulation and a subsequent devoicing.
