Abstract

Recent work showing that a period of perceptual training can modulate the magnitude of speech-motor learning in a perturbed auditory feedback task could inform clinical interventions or second-language training strategies. The present study investigated the influence of perceptual training on a clinically and pedagogically relevant task of vocally matching a visually presented speech target using visual-acoustic biofeedback. Forty female adults aged 18-35 yr received perceptual training targeting the English /æ-ϵ/ contrast, randomly assigned to a condition that shifted the perceptual boundary toward either /æ/ or /ϵ/. Participants were then asked to produce the word head while modifying their output to match a visually presented acoustic target corresponding with a slightly higher first formant (F1, closer to /æ/). By analogy to findings from previous research, it was predicted that individuals whose boundary was shifted toward /æ/ would also show a greater magnitude of change in the visual biofeedback task. After perceptual training, the groups showed the predicted difference in perceptual boundary location, but they did not differ in their performance on the biofeedback matching task. It is proposed that the explicit versus implicit nature of the tasks used might account for the difference between this study and previous findings.
