二語聲調處理歷程的感知同化效應

PERCEPTUAL ASSIMILATION EFFECTS ON L2 TONAL PROCESSING

本研究探討粵語母語者對華語聲調的感知機制。實驗一，粵語母語者聽到華語聲調後辨識所聽到的是哪個聲調。實驗二，評比所聽到的華語和粵語聲調配對的相似度。研究發現，聲調感知的混淆偏誤可能不只來自於聲調之間相近的聲學特徵，也來自於母語和二語聲調對比之間的感知同化程度。基於研究結果，本文討論母語韻律系統對於二語感知的作用，以及感知同化類型如何預測字詞聲調範疇的感知表現。

The goal of this study is to expand our understanding of cross-linguistic comparison in non-native speech perception, focusing on perceptual assimilation at the suprasegmental level. The current study investigates perception of Mandarin tones by Cantonese listeners. In Experiment 1, Mandarin tones were presented and the Cantonese listeners were requested to identify which tone they heard. In Experiment 2, the Cantonese listeners were instructed to rate how similar each Mandarin tone was to a Cantonese tone on a 1 to 5 scale subjectively. The results suggest that tonal confusion errors may result from not only the similar acoustic properties of tone pairs but also perceptual assimilation between L1 and L2 tonal contrasts. Tone 1 and Tone 4 in Mandarin were both rated as the most similar to Tone 1 in Cantonese. Tone 2 and Tone 3 in Mandarin were perceived as belonging to the overlapping set of Cantonese tonemes. The findings are discussed in terms of the effects of the L1 prosodic system on L2 perception. Additionally, the discussion explores how perceptually assimilation patterns can predict listeners' perception performance in the domain of lexical tones.
