System-user interaction and response strategy in spoken dialogue system
نویسندگان
چکیده
There are a number of restrictions in human-machine interactions, which continue to warrant a better control of response utterances in spoken dialogue systems. Indeed, the human user often has to deal with unnatural responses, and therefore requires some experience with such systems in order to improve interactions. This problem is re-examined here, with the aim of evaluating how human users are in uenced by utterances built into a system based on the Wizard-of-Oz method. We report results which show that back-channel responses and brief con rmations from our system, have the e ects of prompting human spoken interactions and providing more human satisfaction.

متن کاملError-correction detection and response generation in a spoken dialogue system
Speech understanding errors in spoken dialogue systems can be frustrating for users and difficult to recover from in a mixed-initiative spoken dialogue system. Handling such errors requires both detecting error conditions and adjusting the response generation strategy accordingly. In this paper, we show that different response wording choices tend to be associated with different user behaviors ...
