Demonstration of the PARLANCE system: a data-driven incremental, spoken dialogue system for interactive search

The Parlance system for interactive search processes dialogue at a microturn level, displaying dialogue phenomena that play a vital role in human spoken conversation. These dialogue phenomena include more natural turn-taking through rapid system responses, generation of backchannels, and user barge-ins. The Parlance demonstration system dierentiates from other incremental systems in that it is data-driven with an infrastructure that scales well.
