This paper presents a progress update of our ISIS trilingual spoken dialog system. ISIS is a conversational system for the stocks domain, and supports interactions in the languages of our region - English and two dialects of Chinese (Mandarin and Cantonese). ISIS provides a system test-bed for our initial explorations with the CORBA architecture, and delegation to KQML agents. CORBA offers the advantages of interoperability, scalability and location transparency in client/server systems development. Users can delegate tasks to software agents to help monitor information (e.g. a drop in the price of a pre-specified stock), and generate user alert messages. Our current work presents new research directions in the context of ISIS: (i) automatic incorporation of newly listed stocks into our system's knowledge base; (ii) switching between on-line interaction and off-line delegation in a single dialog thread. We will also report on enhancements in the system's architecture and features.
