Voiced labio-velar approximant to Voiceless bilabial plosive

The transformation from a voiced labio-velar approximant ([w]) to a voiceless bilabial plosive ([p]) is a type of fortition, where a sound becomes 'stronger' by increasing its degree of stricture. This shift also involves devoicing, as the voiced approximant becomes a voiceless plosive. The change from labio-velar to bilabial indicates a simplification of the place of articulation to a purely labial one.
