The prototype of human - Robot interactive voice control system

This contribution shows our recent activities of human - robot voice-control system. The keynote lays in design of a system that allows easy control and programming of various robots by a uniform interactive interface. Generally the robots are actuated by sets of control commands, sometimes by a manual control interface (touchpad, joystick). The operator has to know the control commands, syntax rules and other properties necessary for successful robot control. Our system offers commands like "move left" or "elevate arm" that are translated and sent into the corresponding device (robot). Speech recognition is based on an isolated-word HMM engine with distributed recognition system (DSR). The vocabulary may contain thousands of word and short phrases. It allows us to design an easy dialogue scenario for the robot control system. The system allows direct robot control like moving or programming short sequences. A video camera is included for displaying the working place and employed algorithms of image processing allow the system to detect the position of objects in the working area and facilitate robot's navigation.
