The embodiment of the invention discloses a model training method for synthesizing speaking expressions. Expression characteristics, acoustic characteristics and text characteristics are obtained according to videos containing face action expressions of speakers and corresponding voices. Because the acoustic feature and the text feature are obtained according to the same video, the time interval and the duration of the pronunciation element identified by the text feature are determined according to the acoustic feature. A first corresponding relation is determined according to the time interval and duration of the pronunciation element identified by the text feature and the expression feature, and an expression model is trained according to the first corresponding relation. The expressionmodel can determine different sub-expression characteristics for the same pronunciation element with different durations in the text characteristics; the change patterns of the speaking expressions are added, the speaking expressions generated according to the target expression characteristics is determined by the expression model.
