Collaborating on Utterances with a Spoken Dialogue System Using an ISU-based Approach to Incremental Dialogue Management

When dialogue systems, through the use of incremental processing, are not bounded anymore by strict, nonoverlapping turn-taking, a whole range of additional interactional devices becomes available. We explore the use of one such device, trial intonation. We introduce a general approach to dialogue management in incremental systems, based on the Information-State-Update approach, and we discuss an implementation in a micro-domain that lends itself to the use of immediate feedback, trial intonations and expansions. In an overhearer evaluation, the incremental system was judged as significantly more human-like and reactive than a non-incremental version.
