2.7 Conclusion

The authors have described our idea for studies on robot audition based on the creation of “the robot that hears a sound with its own ears” and expectation for future development. Since the robot audition study started from almost nothing, we have attempted to promote not only our own study but also the studies concerned We garnered the cooperation of the academia of Asano (AIST), Kobayashi (Waseda University) and Saruwatari et al.(NAIST), enterprises developing robot audition such as NEC, Hitachi, Toshiba and HRI-JP, and furthermore of overseas research institutes such as University of Sherbrooke in Canada, KIST in Korea, LAAS in France and HRI-EU in Germany and have organized the sessions for robot audition in IEEE/RSJ IROS for the past six years and the special sessions in academic lectures of the Robotics Society of Japan for the past five years. Furthermore, in 2009, we organized the robot audition special session in ICASSP-2009, the International Conference on Acoustics, Speech and Signal Processing organized by IEEE Signal Processing Society. Raising such a study community, researchers have been increasing slowly in the world and above all the high level of Japan’s robot audition studies is outstanding. We expect that Prince Shotoku robot will support hearing-impaired persons and elderly people and furthermore contribute to the construction of a peaceful society through more and more future development of our study.

Learning to listen to what others say at sixty years old, from “The Analects of Confucius / Government”
It is said that a person learns to listen to what others say at age sixty. However, the sensitivity of auditory organs for high frequencies drops through overwork or age, and the person loses the ability to hear conversations so he/she cannot depend on their ears even if they wish to.
