ABSTRACT
Speech sound classified according to its manner of articulation, namely intermittent articulation through the vibration of the lower lip, the tip of the tongue, or uvula against the upper lip (or upper teeth), alveolar ridge, hard palate (or back of the tongue), cf. [r] in Italian ['ro:ma] Roma ‘Rome’; the fricative vibrant [r] in Czech ['dvora:k] Dvořák. The trilled r-sounds in Spanish, French, and German are vibrants.
