Development and experimentation on speech sounds and degree of lip rounding system for "H&Frobot-III" humanoid head portrait robot

Abstract

For the further study on the problems of behavior intelligence of apery organs of head and of facial expressions and of the communication of robot with mankind,the problems of introducing for the first time the degree of lip rounding and its speech harmonization into the expression robot system,and the researches were carried through.On the basis of robot system HFrobot-II,which possesses facial expression and visual humanoid head portrait that has already been successfully developed,and in accordance with the muscle anatomy of human facial movements and with the coding system FACS of Ekmen facial expression,the setting up of driving points of lip movements and the degree of lip rounding driving mechanism and its controlling method were discussed.The speech and degree of lip rounding system were designed and developed.Finally the harmonization experimental results of speech recognition and degree of lip rounding for robot HFrobot-III were presented.Its degree of lip rounding could tally nicely with the degree of lip rounding for persons that spoke the same saying.The feasibility of the speech and degree of lip rounding system was testified,thus laid a technological foundation for the further study on the expression intelligence of robots.
