藤县粤语精母字的内爆音

On the Implosives [d—t] in Cantonese of Tengxian

汉语方言中的内爆音多出现在古帮、端母字,广西藤县粤语的精母字也出现内爆音。在县城,老派端、精母字分别为d、t声母,构成最小对,如,赌端du^3≠祖精tu^3;新派中不对立,端精母字声母属同一音位,有的人大多为内爆音变体,有的大多为清爆音变体。另外,新派中相当一部分人虽在心理上认为端、精母字都读同一声母,但事实上处于不稳定状态,同一个字有时读内爆音、有时读清爆音。新派的精母字读内爆音声母是新近时期才产生的,条件是阴调类的不送气清爆音且VOT值接近0,可能与语言接触有关,但并不一定受到壮侗语等其他语言的影响。

Implosives usually occur in two kinds of Chinese characters： Gubang and the initials of Duan（端） Characters. There are implosives in the initials of Jing（精）characters in the Cantonese of Teng County,Guangxi. In the head City of Teng County,there are old party and new party according to the different pronunciations of the initials of Duan（端）and Jing（精）characters. The initials of Duan（端） and Jing（精） are read as/d/,/t/respectively by the old party,which the forms a minimal pair[d—t],such as,赌端du^3≠祖精 tu^3. For the People of the new party,the pronunciation of the initials of Duan（端）and Jing（精）has no difference,which belonging to the same phoneme,cannot form a minimal pair [d—t]. Some people of the new party pronounce the initials of Duan（端）and Jing（精）as/d/which is the variant of voiced implosives and the other as/t/which is the voiceless implosive.Besides,in spite of the fact that some people psychologically regard the initials of the Duan（端） and Jing（精） characters as the same initial consonant,the pronunciations of the initials of the Duan（端） and Jing（精） characters have nuance. Even the same character sometimes may be read as/d/,and other times as/t/. The recent arising of the new implosives in the Cantonese of Tengxian results from the unaspirated plosives with the yin tones and whose VOT are close to 0. Furthermore,the arising of the implosive may be closely related to language contact,but not necessarily be influenced by Zhuangdong languages.
