| Abstract(in English) | A new type of noise reduction method suitable for autonomous mobile robots is proposed and applied to pre-processing of a hands-free spoken dialogue system. The proposed method can reduce various kinds of noise such as directional noise, diffuse noise, moving noise of the robot, and speech utterance from the robot, which are mixed with the target speech for the case in which people talk with the robot, by using small and light-weighted devices and low-computational-cost algorithms. Here, we assume that the people talking with the robot is in the front of the robot, and thus the proposed method aims at extracting speech signals coming from the frontal direction of the robot. In addition, for the case in which the people moves from the front of the robot, the sound source can be localized by face detection and tracking using facial images obtained from a camera mounted on eyes of the robot. By taking advantage of the robot, which can combine speech information with image information, real-time reduction of the various noise can be achieved, and thus the hands-free spoken dialogue system can work well in real environments. |
