Computer-based interviewing systems could use models of respondent disfluency behaviors to predict a need for clarification of terms in survey questions. We compare simulated speech interfaces that use two such models - a generic model and a stereotyped model that distinguishes between the speech of younger and older speakers - to several non-modeling speech interfaces in a task where respondents provided answers to survey questions from fictional scenarios. Our modeling procedure found that the best predictor of conceptual misalignment was a critical Goldilocks range for response latency, outside of which responses are more likely to be conceptually misaligned. Different Goldilocks ranges are effective for younger and older speakers.

Conceptual Mismatches and Repair in Human-Computer Interaction
We present a computational framework for the generation of elementary speech acts to establish conceptual alignment between a computer system and its user. We clearly distinguish between two phases of the alignment process: message interpretation and...

We present a computational framework for the generation of elementary speech acts to establish conceptual alignment between a computer system and its user. We clearly distinguish between two phases of the alignment process: message interpretation and message generation. In the interpretation phase, presuppositions are extracted from the user’s message and compared with the system’s ontology. Subsequently, in the generation phase, an adequate feedback message is produced in order to resolve detected discrepancies. We provide a conversational strategy that is based upon Gricean implicatures and a distinction between three types of beliefs: private beliefs about the domain of discourse, beliefs about the beliefs of the other and beliefs about the shared beliefs.
