Abstract

Audiovisual training in non-native speech discrimination was conducted on 10 native Japanese adults using audiovisual recordings of 14 native English speakers articulating 90 rl word pairs, and analysis of changes in articulatory, acoustical, perceptual and cortical representations of native and non-native phonetic contrasts was performed. Results indicated that perceptual categorization of articulatory movements and resulting phonetic sounds is listener-dependent in a language-specific way, but categorization can be plastically modified even in adulthood through training. Based on these findings, the usefulness of acoustic approaches for proper assessment of communicative values of disordered articulations is discussed.
