Bilabial Trill Induced by Fricative High Rounded Vowel: The Emerging of "TB" in the Wu Dialect of Su-Wan Boundary

This paper describes the phonetic properties of "Tʙ" in the Wu dialect of Jiangsu and Anhui provinces of China (Su-Wan) boundary and discusses the articulation conditions of "Tʙ" in phonetics. We argue that the consonant, mainly the voiceless apico-alveolar plosives or affricates [t/ts/tʃ] as well as their aspirated counterparts tend to undergo trillization. On the other hand, at least three features [+high] [+rounded] [+fricative] for the vowels should be guaranteed. It is further argued that unlike the claim of Ladefoged and Everett (1996), "Tʙ" is not rare in the world's language, but yields a high relevance to the friction of the high rounded vowel.

摘要:

本文描写了苏皖边界吴语"Tʙ"的语音性质以及"Tʙ"声学上的发音条件。 我们认为，从辅音上看，主要是清舌齿塞音和塞擦音[t/ts/tʃ]，以及各 自相应的送气音易发生唇颤。另一方面，元音则至少具备[+高][+圆 唇][+摩擦化]三个特征。本文进一步认为，与Ladefoged 和Everett (1996) 所说的不同，"Tʙ"在世界语言中并不罕见，"Tʙ"的产生与圆唇高元音 的摩擦化密切相关。
