本研究聚焦中韩英语学 习者的英语元音感知与发音 表现，以第二语言习得相关 理论为支撑，对比分析中英 韩三语的元音系统特征，明 确二语“相似元音”与“全新 元音”的判定假设。研究选 取三类受试群体，设计母语 元音产出、中韩学习者元音 识别、本族语者对学习者元 音产出辨识三项关联实验， 结合听辨统计与声学测量多 维度采集数据，系统考察两 类学习者对英语单元音、双 元音的感知准确率、发音表 现异同，以及感知能力与产 出水平的相关关系。研究验 证了二语语音习得经典假设 对中英、中韩元音跨语言迁 移现象的解释力，明确了不 同母语背景学习者习得英语 元音的共性难点与特异性偏 差。本研究弥补了以往同领 域研究多单独聚焦单一母语 学习者的局限，所得结论可 为面向中韩学习者的EFL语 音教学提供实操性参考，也 为二语语音习得领域的对比 研究提供本土化实证依据。
