Abstract(in English) | WE present a dialogue control method called the "dual-cost method", by which a spoken dialogue system carries out an efficient dialogue within the confines of the data stored as the system's knowledge in its database. Due to speech recognition errors, a spoken dialogue system has to carry out a "confirmation dialogue" to clarify a user request. previous methods have a problem of invoking unnecessary confirmations, since they attempt to confirm the whole contents of a user request even though the request is beyond the system's knowledge. To resolve this problem, we introduce the notions of confirmation cost and information transfer cost. The confirmation cost is the length of a confirmation dialogue and depends on the speech recognition rate. The information transfer cost is the length of a system response after the confirmation dailogue and depends on the system's knowledge. The dual-cost method controls a dialogue based on the minimization of these two costs and can avoid unnecessary exchanges, which are inevitable in conventional methods. |
