Abstract

This paper studies the characteristics of the dynamic lip shape of vowels in the Tibetan Xiahe dialect, and illustrates some relationships between vowels through experiments. The experimental results show that the value of the lip width is large when flattened vowels are pronounced, while it is smaller when rounded vowels are pronounced. The lip height is an important indicator to distinguish each vowel. The lip protrusion is prominent in distinguishing rounded vowels. When flattened vowels are pronounced, the protrusion of both lips is smaller than the natural state while the protrusion of the lips is larger than the natural state when rounded vowels are pronounced. The value of the mouth corner stretch and the protrusion value of the lower lip have a certain similarity. If the protrusion of the lower lip cannot be obtained, the value of the mouth corner stretch can be used to judge the changes of the lower lip protrusion. In addition, the experimental results show that it is feasible to collect the dynamic three-dimensional coordinate data of the lip shape of the speakers with the help of high-precision equipment to study the dynamic characteristics of the lip shape in linguistics.
