Voiceless alveolar fricative to Voiced palatal approximant

The transformation from a voiceless alveolar fricative ([s]) to a voiced palatal approximant ([j]) is a documented phonetic shift, often resulting from processes of palatalization and lenition. This change involves a shift in the place of articulation from alveolar to palatal, a reduction in the degree of stricture from fricative to approximant, and a change in voicing from voiceless to voiced.

Language Examples

siching→jisi— This example from the Topo dialect illustrates a phonological modification where an original /s/ sound in a related form corresponds to /j/, as part of a broader consonant shift reflecting Proto-Tanyi heritage.
