Voiceless retroflex stop to Alveolar trill

The shift from a retroflex stop [ʈ] (or its voiced counterpart [ɖ]) to a rhotic sound is a classic form of lenition. In intervocalic positions, the complete closure of the stop is often replaced by a brief tap or flap [ɽ], which is acoustically and articulatory identical to a rhotic consonant in many languages.
