Turn-taking phenomena in incremental dialogue systems
Hatim Khouzaimi, Romain Laroche, Fabrice Lefèvre · 2015
In this paper, a turn-taking phenomenon taxonomy is introduced, organised according to the level of information conveyed.It is aimed to provide a better grasp of the behaviours used by humans while talking to each other, so that they can be methodically replicated in spoken dialogue systems.Five interesting phenomena have been implemented in a simulated environment: the system barge-in with three variants (resulting from either an unclear, an incoherent or a sufficient user message), the feedback and the user barge-in.The experiments reported in the paper illustrate that how such phenomena are implemented is a delicate choice as their impact on the system's performance is variable.
