香港人學習普通話的聲調偏誤之聲學分析

本文首次系統地使用聲學實驗的方法，對香港人學習普通話的聲調偏誤進行量化分析，探討三種語境下的普通話聲調：單字調、句末位置以及句中位置，測量和比較其 f₀（Hz）和時長（秒）數據。實驗結果表明不同的語境對香港人普通話聲調的偏誤有重要影響，在句中位置偏誤最為明顯，尤其體現為第二調和第三調非常接近，這兩個聲調在句中很容易混同。本文的聲學實驗研究，能對粵港澳地區母語為粵語的發音人學習普通話發音提供重要參考。
This is the first systematic acoustic analysis of Putonghua tone errors produced by Hong Kong speakers. Putonghua tones produced in three contexts were investigated: isolated citation form, in the middle of a sentence, and at the end of a sentence. Acoustic data of f₀ (Hz) and duration (s) were measured and analyzed. The results showed that different contexts have an important effect on tone error patterns. There are more severe tone errors in the middle of a sentence, especially the pitch contours of Tone 2 and Tone 3 are very close in the middle of sentence, which seem very likely to be merged. The studies conducted here provided an accurate description of Putonghua tone errors made by Hong Kong speakers in different contexts, which resulted in reasonable suggestions for teaching and learning strategies for them.
