Multiple mobile robot interface using a low cost voice recognition chip

Voice is one of the convenient methods for communicating between humans and robots. To command a lot of robot tasks by voice, voices of the same number have to be able to be recognized. But the more voices that have to be recognized, the higher the cost of recognition system is and the longer the time of recognition is. In this paper, a low cost voice recognition system which can distinguish a lot of robot tasks is proposed. The proposed system consists of a general purpose microprocessor and a low cost voice recognition processor which can recognize a limited number of voice patterns. Given multiple robots, each robot task is classified and organized such that the number of robot tasks under each directory is not more than the maximum recognition number of the voice recognition processor so that robot tasks under each directory can be distinguished by the voice recognition processor.
