项目摘要

Learners of a foreign language (L2) often retain pronunciation errors even after extensive experience with the target language. The proposed project aims at explaining the apparent paradox that, frequently, learners are able to perceive pronunciation errors of fellow learners, yet they are unable to correct the same errors in their own production. Although a large amount of research is concerned with socio-economic factors affecting suboptimal attainment in learning an L2, cognitive factors involving general mechanisms of speech processing remain widely unexplored. None of the current models of L2 sound acquisition sufficiently accounts for a persistent perception-production asymmetry in the L2. The proposed project will close this gap by assessing two potential causes for this asymmetry: (1) deficits in using auditory feedback for error monitoring, and (2) the nature of phonetic category representations. (1) will address whether L2 learners have difficulties in correcting their productions because they are not aware of their own errors. It will be tested whether listeners have more trouble detecting and processing errors when listening to their own voice compared to other learners' voices. (2) will determine how experience with certain mispronunciations affects the association between phonetic categories and lexical representations. It will also assess whether newly established L2 categories that are not present in the native language (L1) or L1 categories that are not present in the L2, nevertheless affect flexibility perception and production in both languages. The methodological innovation here is to test L2 production under online-altered auditory feedback. That is, participants will be presented with a feedback signal that, through signal-processing techniques, mismatches their actual production. Resulting compensatory articulation will speak to error monitoring as well as to the nature of category representations as this method is sensitive to the distribution of phonetic categories in L1 - and as will be determined here - potentially also in L2. The long-term significance of the project is that it contributes to a central debate in cognitive neuroscience and speech processing about the relation of speech production and perception. It will reveal the workings of auditory feedback and error monitoring in L2 processing. In addition, it has the potential to inform strategies in language teaching.

即使经过广泛的目标语言经验，外语的学习者（L2）也会保留发音错误。拟议的项目旨在解释明显的悖论，即学习者经常能够感知其他学习者的发音错误，但他们无法纠正自己的作品中相同的错误。尽管大量的研究与影响L2次优的社会经济因素有关，但涉及语音处理的一般机制的认知因素仍未得到广泛探索。 L2声音采集的当前模型均未充分说明L2中持续的感知产生不对称性。提出的项目将通过评估这种不对称的两个潜在原因来缩小这一差距：（1）使用听觉反馈进行错误监视的缺陷，以及（2）语音类别表示的性质。（1）将解决L2学习者是否在纠正其作品方面是否有困难，因为他们不了解自己的错误。与其他学习者的声音相比，听众在收听自己的声音时是否有更多麻烦在检测和处理错误时会进行测试。（2）将确定某些错误发音的经验如何影响语音类别和词汇表示之间的关联。它还将评估新建立的L2类别是在L2中不存在的本地语言（L1）或L1类别中是否存在的L2类别，但仍影响两种语言的灵活性感知和生产。这里的方法论创新是在在线改变的听觉反馈下测试L2生产。也就是说，参与者将出现一个反馈信号，通过信号处理技术，他们的实际生产不匹配。由此产生的补偿性发音将与错误监测以及类别表示的性质有关，因为该方法对L1中语音类别的分布敏感 - 并且在这里将确定 - 也有可能在L2中进行确定。该项目的长期意义在于，它在认知神经科学和言语处理中就语音生产和感知关系做出了核心辩论。它将揭示L2处理中听觉反馈和错误监视的工作。此外，它有可能为语言教学的策略提供信息。
