Research on language-specific tuning in speech perception has focused mainly on consonants, while that on non-native vowel perception has failed to address whether the same principles apply. Therefore, non-native vowel perception was investigated here in light of relevant theoretical models: the Perceptual Assimilation Model (PAM) and the Natural Referent Vowel (NRV) framework. American-English speakers completed discrimination and native language assimilation (categorization and goodness rating) tests on six nonnative vowel contrasts. Discrimination was consistent with PAM assimilation types, but asymmetries predicted by NRV were only observed for single-category assimilations, suggesting that perceptual assimilation might modulate the effects of vowel peripherality on non-native vowel perception.
语音感知中特定语言调谐的研究主要集中在辅音上，而关于非母语元音感知的研究未能探讨相同的原则是否适用。因此，本文根据相关理论模型——感知同化模型（PAM）和自然参照元音（NRV）框架，对非母语元音感知进行了研究。以美式英语为母语的人完成了对六种非母语元音对比的辨别以及母语同化（分类和好感度评级）测试。辨别结果与PAM同化类型一致，但NRV预测的不对称性仅在单类别同化中观察到，这表明感知同化可能会调节元音边缘性对非母语元音感知的影响。
