摘要
本文对壮语北部方言红水河土语中存在的内爆音(implosive)现象从声学表现和声学分析上进行了研究。按照传统观点,内爆音的发音机制主要是内爆塞音口腔闭塞期间喉头的下降造成口腔负气压(相对于外界气压),口腔打开后引起外围气流被"吸入"。本文对壮语北部方言红水河土语中13对清辅音/内爆音严整对立的单音节词(元音和声调均相同)从声波图表现、语图表现、元音音高和功率的角度进行了声学比较分析。结果显示,与传统的观点不同,内爆音的关键(crucial)发音机制可能是基于发声时通过下声门的气流和气压增大造成的,而且造成音节内元音强度显著增大,而口腔负气压引起的外围气流被"吸入"等表现仅仅是次要和伴随特征。内爆音与其说是承载于辅音,不如说是承载于整个音节的发音机制,而且是一种肺部气流机制的音。
This paper presents research results on implosives existed in the north dialect of Zhuang language.According to traditional theory,in the articulation process of implosive, the sudden drop of glottis increases oral cavity and causes negative oral air pressure and airflow is absorbed after oral closure is released.After analysis of sound wave,spectrograph, vowel pitch and power in implosive syllable of Zhuang language,we maintain that the crucial mechanism of implosive is probably the continuous enhancement of sub-glottal airflow and pressure.As a result,the intensity,power and pitch of vowel in the implosive syllable are remarkably increased(compared with vowel in non-implosive syllable).Features,such as drop of glottis and negative air pressure esc are only accompanying features of implosive mechanism.Instead of attaching to consonant,implosive mechanism exists through the whole syllable.
