摘要
随着科学技术的进步和先进仪器的出现,语音研究逐渐向借助高精尖仪器探索产生机制和声学特性的方向发展。超声成像技术作为一种实时观测发音生理机制的有效方法,为元音的可视化研究提供了新的可能。目前,面向藏语康方言的元音研究大多还停留在依靠单一的生理参数描写或声学特征定义阶段。因此,文章以藏语康方言中五个元音为研究对象,采用同步分析超声舌位图像和声学信号的方法,系统地研究了康方言元音的发音生理表现和声学区别特征,并通过康方言元音格局阐述了元音舌位变化和语音性质之间的基本关系,明确了基于多模态生理语音数据实现元音生理语音验证的可行性,为之后藏语现代语音学的研究和应用提供了有力支撑。
With the advancement of science and technology and the emergence of advanced instruments, speech research is gradually moving toward exploring the mechanisms of production and acoustic properties with the help of highly sophisticated instruments. As an effective method to observe the physiological mechanisms of articulation in real time, ultrasound imaging technology provides new possibilities for the visualization of vowels. At present, most of the vowel studies oriented to Tibetan language are still at the stage of relying on single physiological parameter depiction or acoustic feature definition. Therefore, this paper takes five basic vowels of the Tibetan Kham dialect as the research objects, adopts the method of simultaneous analysis of ultrasonic tongue position images and acoustic signals, systematically investigates the physiological performance and acoustic differentiation characteristics of the basic vowels of the Kham dialect, and elaborates the basic relationship between vowel tongue position changes and phonological properties using the Kham dialect vowel pattern, clarifies the physiological phonological verification of vowels based on multimodal physiological phonological data. The feasibility of phonological verification of vowels based on multimodal physiological phonological data is clarified, which provides a strong support for the subsequent research and application of modern phonology in Tibetan.
