Abstract

The embodiment of the invention discloses a virtual character expression driving method and system. The method comprises the following steps: acquiring voice information of a user; analyzing the volume information of the voice information to obtain character information of the voice information; performing volume analysis on volume information in the voice information to obtain a corresponding mouth shape expression instruction; combining the character information of the voice information and the corresponding mouth shape expression instruction for semantic calculation to obtain a response; and converting the obtained response into response voice, and converting the response voice into expression and mouth shape animation data to drive the virtual character to make a corresponding expression and mouth shape. Generation of expression animations is simplified, and the invention can be widely applied to scenes such as intelligent sound boxes, intelligent robots and chat robots, so that the products are personified and have emotional interaction experience.

Description

technical field [0001] The embodiments of the present application relate to the technical field of artificial intelligence, and in particular to a method and system for driving expressions of virtual characters. Background technique [0002] With the development of big data and deep learning technology, speech recognition and voiceprint recognition are increasingly used in various industries, including target task confirmation, voice unlocking, intelligent voice robot and other industries, as well as intelligent human-computer interaction, voice control Robots, smart home voice wake-up, etc. With the continuous development of deep learning technology, voiceprint recognition and speech recognition technology have appeared many products that affect people's lives, and have increasingly affected human life. [0003] The traditional mouth shape and expression drive need to be cooperated by the model. For example, by shooting the mouth shape of the model with different expression...
