| Outline of Final Research Achievements |
This study investigated how a learner’s native language phoneme inventory affects the perception and production of second language speech sounds. We sought to determine whether the addition of novel phonemes through L2 acquisition causes a restructuring of the perceptual map, thereby altering the perceptual space and the mapping of acoustic features to segmental categories, including native language phonemes. Perceptual experiments with L1 Chinese- and L1 Japanese-speakers showed that native language inventories dictate L2 perceptual confusion and further suggested that learning an L2 leads to restructuring of the perceptual map. In addition, spectrographic analysis of acoustic features in the production of L2 sounds that are similar to L1 segments showed that the precise acoustic features change depending on a learner’s stage of acquisition.

L2音声習得による母語の音韻文法への影響は主に母音発話、およびVOT発話の音響分析による研究が行われてきた。代表者らの一連の研究は、摩擦音を対象とした研究であり、知覚・生成の両面からL２音が母語の音声マップに追加される過程でどのような変化が起こるのかを明らかにする試みであった。結果は知覚マップの再構成が起こることを示唆するものであり、第二言語を学ぶ過程でおこる変化を明らかにする手がかりとなろう。
