舌尖化是汉语方言典型的音变形式之一,但对这一现象的载体———舌尖元音的性质目前认识还不够充分。本文以舌尖元音[]为代表,从实验角度分析了汉语方言中的舌尖元音类型,发现舌尖元音与舌面元音[i]一样,存在四种变体形式:无擦、弱擦、较强擦、强擦。这四种变体形式可以有效地解释舌尖化音变在汉语方言中的不平衡现象。 Lingualization is one of the typical forms of Chinese dialects, but the nature of tongue vowels, the carrier of this phenomenon, is not yet fully understood. In this paper, the vowel [] of the tongue is taken as the representative to analyze the tongue vowel types in the Chinese dialect from the experimental point of view. It is found that vowel vowels of the tongue have the same variations as the vowel [i] Rub, stronger rub, rub strong. These four variants can effectively explain the tongue-like sounding imbalance in Chinese dialects.
