【摘要】：本研究利用语音编辑合成技术和言语理解实验,考察了不同背景噪音对二语学习者汉语言语理解的影响。结果发现:对于背景噪音的干扰作用,不能笼统概括为从能量掩蔽到信息掩蔽的简单梯度效应;背景噪音所包含的词汇语义信息对二语学习者的言语理解会带来明显干扰,但整句语义信息并不会带来额外影响;初级和高级汉语水平学习者仅在词列句条件下的差异不显著,其他条件下的差异都显著。上述结果表明背景噪音对二语学习者言语理解的影响既受到噪音本身所包含信息的制约,也受到学习者汉语水平的调节。研究结果有助于进一步揭示背景噪音对二语言语理解掩蔽效应的作用机制,对二语教学实践也有积极的参考价值。
[Abstract]:In this study, the effects of background noise on Chinese speech comprehension of second language learners were investigated by using speech editing and synthesis techniques and speech comprehension experiments.The results show that the interference effect of background noise cannot be generalized as a simple gradient effect from energy masking to information masking, and that the lexical semantic information contained in background noise will significantly interfere with L2 learners' speech comprehension.However, the semantic information of the whole sentence will not bring additional influence; the differences between primary and advanced Chinese learners are not significant only under the lexical column conditions, but the differences under other conditions are all significant.The results show that the influence of background noise on L2 learners' speech comprehension is not only restricted by the information contained in the noise itself, but also regulated by the learners' Chinese proficiency.The results are helpful to further reveal the mechanism of background noise on the masking effect of second language comprehension, and also have positive reference value to the practice of second language teaching.
