Disclosed are system and method of remotely controlling the home appliance by employing the voice/character recognition technique. The appliance detects a connection relationship between the appliance and the mobile terminal and dynamically transmits the control code and a module for transmission. If the appliance control command is inputted through the voice control command input screen or the handwriting control command input screen, after the inputted command is interpreted through the voice/character recognition technique and is transformed to the control code of the appliance to be sent to the home appliance, the control code is sent to the home appliance to remotely control it. The function thereof may be extended to the environment capable of implementing the bi-directional communication with the appliance by receiving the control code from the appliance, while overcoming the limitation of the conventional terminal having a fixed function. In addition, since it is easy to add or delete the control function, a plurality of appliances can be effectively controlled by use of one terminal.
