Abstract: | Applications with intelligent conversational virtual humans, called Embodied Conversational Agents (ECAs), seek to bring human-like
abilities into machines and establish natural human-computer interaction. In this paper we discuss realization of ECA multimodal
behaviors which include speech and nonverbal behaviors. We devise RealActor, an open-source, multi-platform animation system
for real-time multimodal behavior realization for ECAs. The system employs a novel solution for synchronizing gestures and
speech using neural networks. It also employs an adaptive face animation model based on Facial Action Coding System (FACS)
to synthesize face expressions. Our aim is to provide a generic animation system which can help researchers create believable
and expressive ECAs. |
