Intelligent barge-in in Conversational Systems

Abstract - In this paper we present novel solutions to problems related to barge-in in telephony-based conversational systems. In particular we address recovery from falsely detected barge-in events and a method for signaling to the user that barge-in is disallowed at a particular dialogue state. The mechanisms and signals used to manage turn taking are similar to those in human-human conversation, which makes them easy to understand for users without explanation or prior training.
