Abstract

A possible perceptual basis for change between coronal and dorsal rhotics was examined. An approximant /r/ continuum was synthesized with F2 and F3 ranging from 'velar' to 'alveolar' values. Listener responses indicated that the observed region was ambiguous in terms of place of articulation. This suggests the existence of a perceptual bridge between coronal and dorsal rhotics which, in turn, may provide a perceptual basis for historical sound change.
