Abstract

This study investigates imitation of English /s/ to determine whether speakers converge toward normalized or raw acoustic targets. Participants exposed to increased spectral mean (SM) raised SM, converging toward both the raw acoustics of the model talker (who had high baseline SM) and the pattern of increased SM. However, after exposure to decreased SM, direction of shift depended on participant baseline. All participants converged to the raw acoustic values of the model talker, increasing or decreasing their own SM accordingly. These results suggest imitation is not necessarily mediated by perceptual normalization to different talkers, and raw acoustics can be the target of phonetic imitation. This has theoretical implications for the perception-production link and methodological implications for analysis of convergence studies.
