| Abstract(in English) | We aim to construct a spoken dialogue system for in-vehicle information system. It is necessary to achieve an efficient spoken dialogue by controlling a mental workload from the viewpoint of safety and immediateness when a driver uses a speech interface under driving condition. In this study, we focused on user's sense of purpose and amount of output information from a system in a restaurant retrieval of a car navigation system and studied the mental workload of the spoken dialogue when a driver uses an in-vehicle information system by speech interface. We conducted spoken dialogue experiments based on the WoZ method and analyzed the mental workload by using dual-task method and NASA-TLX. As a result, it demonstrated that the mental workload increased when the amount of speech information by the system were large and user's sense of purpose were low. |
