Abstract:
Currently, most spoken dialogue systems only deal with the interaction between
the system and one speaker. In some situations, interactions may occur between
several speakers and the system. New functions and improvements need to be
made in order to handle a multi-user situation. Studies of the human computer
interaction system that involve multiple users are in their initial stages and any
papers, lectures or studies on the subject are very limited. For these reasons we
are motivated to conduct a further study on multi-speaker dialogue systems. In
this chapter, the interactions between the multiple speakers and the system are
classified into three types: independent, cooperative, and conflicting
interactions. An algorithm for the multi-speaker dialogue management is
proposed to determine the interaction type, and to keep the interaction going
smoothly. The experimental results show that the proposed algorithm can
properly handle the interaction that occurs in a multi-speaker dialogue system,
and provides useful vehicular information to the speakers.
