【摘要】：本研究以彝语北部方言的松紧元音为研究对象,全面考察了松紧元音对立的产生机制。研究中使用喉头仪(Electroglottography)采集声源信号,使用超声仪对松紧元音发音过程中的舌头运动进行观测。研究结果表明:(1)彝语北部方言松紧元音在发声类型上有显著区别;(2)根据彝语松紧元音共振峰的声学元音图可以推测松元音的舌位高于紧元音,并且松元音舌位比紧元音更靠前;(3)通过使用超声仪器观测进一步证实了松元音的舌位比紧元音靠前靠上的声学推测。因此,从言语产生的生理过程看,彝语松紧元音的对立也许不完全是因为不同的发声类型,舌头的调音部位可能也起着一定的作用。
[Abstract]:In this study, the formation mechanism of the tense vowels in the northern Yi dialect was investigated. In this study, the sound source signals were collected by Electroglottography, and the tongue motion was observed by supersonic instrument in the process of pronunciating loose and tight vowels. The results show that: (1) there are significant differences in the phonetic types of loose and compact vowels in the northern Yi dialect, (2) according to the acoustic vowels of the resonance peaks of the loose and compact vowels in the Yi language, it can be inferred that the tongue position of the loose vowels is higher than that of the compact vowels. The tongue position of the loose vowel is more forward than that of the compact vowel. (3) the acoustic conjecture that the tongue position of the loose vowel is higher than that of the compact vowel is further confirmed by using the ultrasonic instrument. Therefore, according to the physiological process of speech, the antagonism of loose vowels in Yi language may not be entirely due to different phonetic types, and the tongue-modulated parts may also play a certain role.
