Backchannel-inviting cues in task-oriented dialogue

چکیده
We examine BACKCHANNEL-INVITING CUES — distinct prosodic, acoustic and lexical events in the speaker’s speech that tend to precede a short response produced by the interlocutor to convey continued attention— in the Columbia Games Corpus, a large corpus of task-oriented dialogues. We show that the likelihood of occurrence of a backchannel increases quadratically with the number of cues conjointly displayed by the speaker. Our results are important for improving the coordination of conversational turns in interactive voice-response systems, so that systems can produce backchannels in appropriate places, and so that they can elicit backchannels from users in expected places.

متن کاملWho Do You Think Will Speak Next? Perception of Turn-Taking Cues in Slovak and Argentine Spanish
We investigate perceptual cues in human-human dialogue management related to signalling the change of speaker and the interlocutor’s wish to backchannel or contribute with propositional content. We are interested primarily in the relevance of prosodic cues in relation to textual ones, and their crosslinguistic validity by comparing unrelated languages Slovak and Argentine Spanish. Results of a ...
