Individual differences in perceptual adaptability of foreign sound categories

摘要: Listeners possess a remarkable ability to adapt acoustic variability in the realization of speech sound categories (e.g., different accents). The current work tests whether non-native listeners their use cues phonetic categorization when they are confronted with changes distribution input, as native do, and examines what extent these adaptation patterns influenced by individual cue-weighting strategies. In line previous work, English listeners, who voice onset time (VOT) primary cue stop voicing contrast 'pa' vs. 'ba'), adjusted f0 (a secondary contrast) noncanonical "accent" which two gave conflicting information about category membership. Native Korean listeners' strategies, while variable, were predictable based on initial weighting particular, used membership VOT (their cue) response accent, mirroring pattern "downweighting" cue. Results suggest that show native-like sensitivity distributional input this adjust categorization, just specific trajectory governed
