The advancement of traffic and computer networks makes the world more and more internationalized and increases the frequency of communications between people using different languages and expressing different nonverbal behaviors. To improve communication of embodied conversational agent (ECA) systems with their human users, the importance of their capability to cover the cultural differences emerged. Various excellent ECA systems are developed and proposed previously, however, the cross-culture communication issues are seldom addressed by researchers. This project aims to explore the possibility of rapidly building multicultural and multimodal ECA inter-faces for customer service applications with a generic framework connecting their functional blocks.
