噪音背景对第二语言学习者汉语词语识别和句子理解的影响

Word Recognition and Sentence Comprehension in Background Noise by Students Learning Chinese as a Second Language

研究考察了噪音背景对第二语言学习者汉语言语理解的影响,发现:汉语水平和信噪比都对学习者噪音背景下的汉语言语理解有重要影响,但对词语识别和句子理解的影响却存在一定程度的差异;无论是在安静环境下还是在噪音背景下,学习者词语识别和句子理解的成绩都与其声调感知的辨别力指数之间存在显著的正相关。基于上述发现,我们认为课堂教学应该适当安排类似真实场景的交际活动以及通过更加有效的教学方法提高声调知觉能力,从而改善学习者噪音环境下的言语理解能力。

This study examines the effects that background noise may have on the compre- hension of Chinese speech by students learning Chinese as a second/foreign language. The results show that while word recognition and sentence comprehension are affected by both proficiency in Chinese and signal-to-noise ratios, learners＇ performances differ to some extent in the two tasks. Furthermore, both word recognition and sentence comprehension correlate positively with lexical tone recognition, no matter whether in quiet or in background noise conditions. On the basis of such findings, we propose that more classroom activities should be designed to simulate real com- munication situations and improve learners＇ ability of tone recognition so that they can better com- prehend Chinese speech in background noise.
