Voiceless alveolar affricate to Voiceless glottal fricative
The phonetic transformation from a voiceless alveolar affricate ([ts]) to a voiceless glottal fricative ([h]) represents a significant sound change, typically categorized as a form of lenition or debuccalization. This shift involves a weakening of the articulatory effort, moving from a complex sound with a complete closure and fricative release at the alveolar ridge to a simpler fricative produced solely at the glottis.
