Alveolar trill to Voiceless uvular fricative

The alveolar trill, commonly known as the 'rolled r,' can undergo a significant transformation in certain dialects, shifting its place of articulation from the alveolar ridge to the uvula and becoming a voiceless fricative. This change involves a series of phonetic adjustments that result in a perceptually distinct sound.

Phonetic Effects

Uvularization, Fricativization, Devoicing

Language Examples

[r:]→[χ]— The geminate alveolar trill, typically represented by orthographic 'rr', is realized as a voiceless uvular fricative. For example, 'arroz' (/aˈrros/) becomes [aˈχos] and 'carro' (/ˈkarro/) becomes [ˈkaχo].
