摘要

method and apparatus for changing the lip shape and obtaining lip animation in voice-activated animation. the present invention relates to a method and apparatus for changing the shape of the lip and obtaining a lip animation in a voice-activated animation and relates to computer technologies. the method for altering the lip shape includes: obtaining audio signals and obtaining proportion of movement extension of the lip shape according to the characteristics of the audio signals; obtain a model of the original lip shape inserted by a user and generate a value of the extension of the lip shape according to the original lip shape model and the proportion of movement extension obtained from the lip shape; generate a set of grid model of the lip shape according to the value of extension of movement of the lip shape obtained and a pre-configured lip pronunciation model library. the method for changing the lip shape in a voice-activated animation includes a retrieval module, a first generation module and a second generation module. the solutions provided by the present invention have a simple and low cost algorithm.
