年龄本研究的目的是确定双语者在语言习得时的年龄如何影响他们语音双语系统的组织。英语和韩语单语者的六个英语和五个韩语元音的生产进行了比较，以生产相同的个体差异元音的早期和晚期韩英双语者不同的暴露量，他们的第二语言。结果表明，双语者的年龄对母语（L1）和第二语言（L2）语音系统之间相互作用的程度和方向都有深刻的影响。特别是，早期双语者表现出双向L1-L2的影响和元音系统产生不同的声学实现L1和L2元音。然而，晚期双语者表现出L1对L2的单向影响的证据，并产生了L2元音，这些元音被他们的L1的声学特性“着色”。早期和晚期双语者的L1-L2影响的程度和方向似乎取决于L1和L2元音之间的声学相似性程度以及它们暴露于L2的长度。总体而言，研究结果强调了双语者L1-L2语音系统重组的复杂性。
age The objective of this study was to determine how bilinguals' age at the time of language acquisition influenced the organization of their phoneticbilingualism system(s). The productions of six English and five Korean vowels by English and Korean monolinguals were compared to the productions of the sameindividual differences vowels by early and late Korean-English bilinguals varying in amount of exposure to their second language. Results indicated that bilinguals' age profoundly influenced both the degree and the direction of the interactionKorean between the phonetic systems of their native (L1) and second (L2) languages. In particular, early bilinguals manifested a bidirectional L1-L2 influence andvowel systems produced distinct acoustic realizations of L1 and L2 vowels. Late bilinguals, however, showed evidence of a unidirectional influence of the L1 on the L2 and produced L2 vowels that were "colored" by acoustic properties of theirL1. The degree and direction of L1-L2 influences in early and late bilinguals appeared to depend on the degree of acoustic similarity between L1 and L2 vowels and the length of their exposure to the L2. Overall, the findings underscored the complex nature of the restructuring of the L1-L2 phonetic system(s) in bilinguals.
