掌握第二语言语音系统的程度因人而异。本研究评估了后期双语者在不同语音过程中的个体差异模式。55晚荷兰-英语双语者进行了测试，他们的能力感知困难的12语音对比（英语/ae/-//对比）在三个不同的任务：分类任务，单词识别任务和词汇决策任务。作为一个群体，12名听众的准确性低于本地听众。然而.在个体水平上，12名被试中有近一半的人在分类任务中得分在母语范围内，而在识别和词汇判断任务中得分在母语范围内的被试只占一小部分。这些结果表明，12名听众的表现主要取决于任务的性质，具有较高的12名听众的准确性上的声学语音分析任务比涉及词汇过程的任务。这些发现平行早期双语者，其中的性能模式是一致的处理层次结构提出的不同模型的语音感知以前的结果。研究结果表明，对非本族语表现模式的分析可以为言语感知系统的结构和语言可学性问题提供重要的见解。(C)2012 Elsevier Inc.

The extent to which the phonetic system of a second language is mastered varies across individuals. The present study evaluates the pattern of individual differences in late bilinguals across different phonological processes. Fifty-five late Dutch-English bilinguals were tested on their ability to perceive a difficult 12 speech contrast (the English /ae/-/epsilon/ contrast) in three different tasks: A categorization task, a word identification task and a lexical decision task. As a group, 12 listeners were less accurate than native listeners. However. at the individual level, almost half of the 12 listeners scored within the native range in the categorization task whereas a small percentage scored within the native range in the identification and lexical decision tasks. These results show that 12 listeners' performance crucially depends on the nature of the task, with higher 12 listener accuracy on an acoustic-phonetic analysis task than on tasks involving lexical processes. These findings parallel previous results for early bilinguals, where the pattern of performance was consistent with the processing hierarchy proposed by different models of speech perception. The results indicate that the analysis of patterns of non-native performance can provide important insights concerning the architecture of the speech perception system and the issue of language learnability.
