Voiceless aspirated alveolar plosive to Alveolar trill

This phonetic transformation involves the lenition of a voiceless aspirated alveolar plosive into an alveolar trill. The process entails a weakening of the articulatory stricture, where the complete closure of the plosive is reduced to a series of rapid contacts against the alveolar ridge, characteristic of a trill. The aspiration feature of the initial plosive is lost during this sound change.
