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。
The study examines the effect of noise background on second language learners’ understanding of Chinese speech, and finds that both Chinese proficiency and signal-noise ratio (S / N) have an important influence on Chinese speech understanding under the background of learner noise. However, the impact on speech recognition and sentence understanding There is a certain degree of difference. There is a significant positive correlation between learners’ word recognition and sentence comprehension scores and their tone-sensing discriminative index, both in a quiet environment and in a noisy background. Based on the above findings, we think classroom teaching should appropriately arrange communicative activities like real scenes and improve the ability of tonal perception through more effective teaching methods so as to improve learners’ speech comprehension ability in noisy environments.
