Remote Control System of Spherical Robot based on Silent Speech Recognition

In the past, people control robots by remote-control or keyboard which is quite difficult and not efficient. This method needs to occupy people's hands and is totally unfriendly to the disabled. So we developed a spherical robot remote control system based on silent speech recognition technology. After the surface EMG signals are collected by the equipment, preprocessed and extracted features, the recognition results which are produced by the random forest are sent to the spherical robot to make it move. By this way, the spherical robot can move according to people's thought without hands' movements. In this paper, the reliability of the system is verified by experiments, which prove it has practical application value.
