Voiced aspirated alveolar plosive to Voiced retroflex stop
The transformation from a voiced aspirated alveolar plosive (dʱ) to a voiced retroflex stop (ɖ) is a documented phonetic shift, primarily observed within the Indo-Aryan language family. This change involves both a shift in the place of articulation from alveolar to retroflex and a loss of aspiration, often triggered by specific phonological contexts.

Assimilation, Deaspiration
Language Examples
/ʂdʱ/→/ɖ/— In Proto-Indo-Aryan, clusters involving a retroflex sibilant /ʂ/ followed by an alveolar aspirated stop /dʱ/ could undergo retroflex assimilation, resulting in a retroflex stop. Subsequent deaspiration of the resulting /ɖʱ/ would lead to /ɖ/. This is supported by the rule ʂ+/t tʰ d dʱ/ > ʂʈ ʂʈʰ (ɖ)ɖ (ɖ)ɖʱ.
