摘要
塞音是汉藏语系语言的辅音中最重要的音素类型。本文利用EGG-D800设备采集藏语康方言塞音的生理语音数据,分析了藏语康方言塞音的声学和生理参数特征。经过分析康方言塞音的语图和EGG信号,首先发现EGG信号的波形图存在识别清音与浊音的作用,得出康方言塞音分为有声浊音和无声清音;其次开商与塞音的“送气”量存在密切关系,根据塞音开闭比提出藏语康方言塞音有4种发声类型,并且得出塞音的开闭比是区别康方言塞音发声类型的重要参数。这些对语音的辅音研究、藏语塞音的发声研究均有一定的理论意义和参考价值。
As the most widely distributed and used consonant phoneme in the Sino-Tibetan language family,the cepstral sound is the most widely used consonant phoneme.In this paper,the physiological phonetic data of Tibetan Kham dialect cepstral sounds were collected using EGG-D800equipment,and the characteristics of acoustic and physiological parameters of Tibetan Kham dialect cepstral sounds were analyzed.After analyzing the phonogram and EGG signal of Kham Plosive,firstly,we found that the waveform of EGG signal has the function of identifying clear and turbid tones,and concluded that Kham Plosive are classified into voiced turbid tones and voiceless clear tones;secondly,there is a close relationship between the opening quotient and the amount of“air delivery”of Plosive,and based on the ratio of opening and closing of Plosive,we proposed that there are four types of vocalizations of Kham Plosive It is suggested that there are four types of cepstral voicing in Kham dialect,and the ratio of cepstral opening to closing is an important parameter to distinguish the types of cepstral voicing in Kham dialect.These studies have some theoretical significance and reference value for the study of consonants and the vocalization of Tibetan cepstral sounds.
