Robot interface learning user-defined voice instructions

The voice interface is a big role in the human robot interaction. However, there are problems; imperfectness, deterioration from unknown words, and so on. In order to compensate imperfectness, the proposed robot behaves familiarly like an infant. For the unknown words, the robot learns user-defined voice instructions by the remote controller trigger. The experimental results show that the proposed method is useful. The results show that the succeeded operation rate exceeds the rate of speech recognition by leaning users´ defined voice instructions. The proposed method is more effective for elderly people than younger people.
