Development and Operation of Speech-Oriented Information Guidance Systems, Kita-chan and Kita-robo
The authors have been operating a real-environment speech-oriented information guidance system named “Takemarukun daily at the Ikoma City North Community Center. The system introduces an example-based one-question-one-answer strategy, noise rejection and an adult versus child user discrimination mechanism. As a result, it realizes robust response generation since its initial operation in Nov. 2002. Following the success of “Takemaru-kun, two additional systems were developed and installed in a railway station, side by side, since Apr. 2006. Although the three systems share the same core software, “Takemaru-kun and “Kita-chan employ CG agents and “Kita-robo has a robot-like body casing. At the railway station, users can talk to the system of their preference. In this paper, we introduce the two later information guidance systems and report their initial operational results including an analysis of user utterances according to age groups. An analytical result shows that children’s utterances to the robot are twice as many as those to the CG agent. In addition to that, it is observed that children do not make difference in question topics between the systems, but adults do.
