Abstract: A voice-controllable image display device comprises: a memory unit for storing therein a database to which identified voice data is allocated and mapped for each execution unit area of a screen displayed through the display unit; a voice recognition unit for receiving an input of a user's voice; an information processing unit for searching the database and determining whether there is identified voice data corresponding to the user's voice when the voice recognition unit receives the user's voice; and a control unit for generating an input signal in the execution unit area to which the identified voice data is allocated if there is identified voice data corresponding to the user's voice as a result of the determination by the information processing unit.

Abstract: The present invention is to provide a voice-controlled display device configured such that the inputted user's speech is compared with the identification voice data assigned to each of the execution unit areas on a screen displayed through a display unit and, if there exists identification voice data corresponding to the user's speech, an execution signal is generated to the execution unit area to which the identification voice data is assigned to resolve the inconvenience that the user needs to learn the voice commands stored in the database and to apply the convenience and intuitive simplicity of user experience (UX) of the conventional touchscreen control to the voice control, and a method of voice control of the above display device
