Abstract |
During the construction of a spoken dialogue system much effort is spent onimproving the quality of speech recognition as possible. However, even if anapplication perfectly recognizes the input, its understanding may be far fromwhat the user originally meant. The user should be informed about what thesystem actually understood so that an error will not have a negative impact inthe later stages of the dialogue. One important aspect that this work tries toaddress is the effect of presenting the systems understanding duringinteraction with users. We argue that for specific kinds of applications itsimportant to confirm the understanding of the system before obtaining theoutput. In this way the user can avoid misconceptions and problems occurring inthe dialogue flow and he can enhance his confidence in the system. Neverthelessthis has an impact on the interaction, as the mental workload increases, andthe users behavior may adapt to the systems coverage. We focus on twoapplications that implement the notion of rephrasing users input in adifferent way. Our study took place among 14 subjects that used both systems ona Nokia N810 Internet Tablet. |
