With the development of cultural industry and computer technology,animation industry is gradually warming,flowers in recent years,more and more animation works,rise in the number of.animation works,also pay more attention to the quality of the audience for works,animation performance standards also constantly improve,the audience is more eager to flesh and blood,soul animated characters.Expression is an important way for animation characters to interact with the audience,and the quality of expression animation is also the key to determine whether the animation performance is natural and vivid.This paper discusses the two ends of expression animation,simple mouth animation,inanimate expression and so on,and puts forward the design and implementation method of expression animation based on voice drive.Firstly,based on the principle of speech recognition,this paper analyzes the pronunciation locations and characteristics of the initials and finals of Chinese piny in,and summarizes 14 types of basic static visual positions.Then the synergistic phenomena in Chinese coherent speech flow are analyzed,and the mutual influence between different phonemes corresponding to the mouth shape is summarized,which provides a theoretical basis for the synthesis of mouth shape animation.Secondly,through detailed case analysis,this paper clarifies the important role of micro expressions in expression animation,summarizes the corresponding relationship between emotions and micro expressions,and puts forward the design basis of micro expressions in two-dimensional animation character performance as well as the design ideas of micro expressions with different facial structures,so as to provide the theoretical basis for the expression creation of animated characters.Finally,this paper applies the theoretical research to two-dimensional facial expression animation and obtains good animation effect. |
