语音型噪音对二语者汉语元音声调感知的影响

在安静、语音型噪音、语音调制型噪音三种背景下测量了汉语母语者、汉语中、高水平的韩语母语者感知汉语元音和声调的正确率。安静背景下，三组人的语音感知类似，而在语音型噪音背景下，汉语母语者的感知正确率显著高于中水平二语者。进一步的检验表明中水平二语者在语音型噪音背景下的感知难度较大是由于其受到的语音型噪音中能量掩蔽的影响比母语被试要大，而其受到的信息掩蔽的干扰和另外两组被试相近。

Informational Masking of Six-talker Babble on Mandarin Chinese Vowel and Tone Identification: Comparison between Native Chinese and Korean Listeners

Identification of Mandarin Chinese speech sounds (vowel-plus-tone) were measured in quiet and two types of noise:six-talker babble and babble-modulated noise, for Mandarin-and Korean-native listeners with high and medium Mandarin proficiency. In quiet, the two groups of Korean-native listeners had similar performance, while in six-talker babble, Chinese-native listeners significantly outperformed Korean-native listeners with medium Mandarin proficiency. Moreover, Korean-native listeners with medium Mandarin proficiency showed greater energetic masking than Chinese-native listeners, but comparable informational masking with the other two groups of listeners, likely resulting in their greater challenges in six-talker babble.
