Voiced alveolar flap to Alveolar trill
The transformation from an alveolar flap to an alveolar trill is a process of fortition or gemination, typically occurring to increase the perceptual salience of a rhotic or as a result of phonemic length contrasts.
Phonetic Effects
Fortition, Gemination, Rhoticization
Language Examples
ɾ→r— In many dialects, a tap can be realized as a trill for emphasis or in specific phonological contexts (e.g., word-initial position where historical taps were strengthened).
-rr- [geminate]→r [trill]— Historical shift where Latin geminate rhotics were reanalyzed as a distinct trill phoneme contrasted with the single tap.
