| Abstract(in English) | As avatars (agents) are beginning to be used in various situations, there is a demand for agents that perform more human-like actions. In this study, we trained various machine-learning models to perform human-like actions in conversations, generated actions using the models, and evaluated the effectiveness of the models. Specifically, we conducted experiments in which two subjects talked with each other and obtained time-series data about the subjects' gazing states and utterances. Using this dataset, we trained models based on HMM and Transformer. Next, we generated behavior of agents in conversations using the learned model, reproduced conversation scenes using a game engine, and subjectively evaluated the naturalness and reality of the generated results. The results showed that the model based on the Transformer can flexibly select actions. |
