Voiceless bilabial plosive to Voiceless alveolar plosive
The shift from the bilabial stop [p] to the alveolar stop [t] is a form of coronalization. While rare as a diachronic law in adult speech, it is a universal phonetic process in child language development, where children substitute the more visible or easier-to-articulate alveolar closure for the bilabial one.
