How was your day? An architecture for multimodal ECA systems.

Multimodal conversational dialogue systems consisting of numerous software components create challenges for the underlying software architecture and development practices. Typically, such systems are built on separate, often preexisting components developed by different organizations and integrated in a highly iterative way. The traditional dialogue system pipeline is not flexible enough to address the needs of highly interactive systems, which include parallel processing of multimodal input and output. We present an architectural solution for a multimodal conversational social dialogue system.
