Abstract This paper describes a perception experiment with Polish listeners involving vowel inherent spectral change (VISC) in L2 English. A forced-choice rhyming task employing the Silent Center (SC) paradigm revealed relatively uniform effects of stimulus type (SC, Initial, Middle, Final) on accuracy across two proficiency groups, despite greater overall accuracy on the part of the more proficient users. Analysis of individual vowel pairs used in the rhyming trials revealed some effects of proficiency on the degree to which formant movement in the stimuli affected identification accuracy. This research contributes to the relatively sparse literature on VISC in L2 acquisition. Phonological considerations underlying the degree of VISC in Polish and English are also discussed.

波兰听众对二语英语中元音固有频谱变化的理解

摘要本文介绍了一种针对波兰听众的感知实验，该实验涉及第二语言中的元音固有频谱变化（VISC）。一项采用沉默中心（SC）范式的强制选择押韵任务显示，两个熟练组的刺激类型（SC，初始，中级，最终）对准确性的影响相对均匀，尽管熟练程度较高的用户总体上具有较高的准确性。对在韵律试验中使用的单个元音对的分析显示，熟练程度对刺激中共振峰运动影响识别准确性的程度有一定影响。这项研究为L2采集中关于VISC的相对稀疏的文献做出了贡献。还讨论了波兰语和英语中的VISC程度所基于的语音方面的考虑。
