Devices for controlling voice and lip language, and control method for voice and lip language

The invention discloses a device for controlling voice. The device comprises an image obtaining and analysis unit, a voice obtaining and identifying unit, and a comparison and output unit. The image obtaining and analysis unit is used to obtain video images of a controlled device, and performs image identification to obtain menus and corresponding coordinates in the images, and outputs the menus and the corresponding coordinates to the comparison and output unit. The voice obtaining and identifying unit is used to obtain voice, and analyzes the voice to obtain characters or figures, and outputs the characters or figures to the comparison and output unit. The comparison and output unit compares the menus received from the image obtaining and analysis unit with the characters or figures received from the voice obtaining and identifying unit, and outputs coordinates corresponding to matched menus to the controlled device, and the controlled device operates according to the received coordinates. The invention also provides the device for controlling lip language, and the control method for lip language. The technical scheme can adapt to control of display screens in all dimensions, and cost would not be increased by increasing of the dimension of the screen. The device and the method provide low-cost and more convenient interaction process for man-machine interaction.
