Meeting browser: a system for visualising and accessing audio in multicast meetings

We describe a tool which provides interactive graphical user-support within an Internet-based virtual meeting place where users may be connected via heterogeneous systems (e.g. workstation, PDA, or mobile telephone) and where spoken language is the main modality of interaction. Communicative turns are integrated with non-acoustic data to form the meeting history. The tool is accessed through a graphical user interface (GUI) component based on a "musical score" metaphor.
