Abstract
This application provides a audio-driven three-dimensional facial animation model generation method and apparatus, and an electronic device. The method includes: acquiring sample data including sample audio data, sample speaking style data, and a sample blend shape value; performing feature extraction on the sample audio data to obtain a sample audio feature; performing convolution on the sample audio feature based on a to-be-trained audio-driven three-dimensional facial animation model to obtain an initial audio feature, and performing encoding on the sample speaking style data based on the to-be-trained audio-driven three-dimensional facial animation model to obtain a sample speaking style feature; performing encoding on the initial audio feature and the sample speaking style feature based on the to-be-trained audio-driven three-dimensional facial animation model, to obtain an output blend shape value; and performing calculation on the sample blend shape value and the output blend shape value to obtain a loss function value.
