Voiced aspirated alveolar plosive to Voiced bilabial plosive

The transformation from a voiced aspirated alveolar plosive (dʰ) to a voiced bilabial plosive (b) represents a historical sound change involving both the loss of aspiration and a shift in the place of articulation. This type of shift, where a sound moves from the alveolar ridge to the lips, is known as labialization or fronting. It is a well-attested phenomenon in the development of certain language families, particularly within Indo-European languages.
