User terminal comprising at least one screen for displaying graphic user interfaces, an operating system, at least one means for capturing a vocal order emitted by the user for the control of an object of the user terminal that can be activated, at least one memory for memorising at least one control database (4, 17, 20), characterised in that the user terminal is configured to carry out the following steps: • at each display of at least one graphic interface on the screen of the user terminal, identifying the objects that can be activated present in said at least one graphic interface thus displayed, and for each object that can be activated: - identifying a piece of descriptive data comprising a piece of location data and a piece of textual data of the object that can be activated, the piece of location data of the object that can be activated allowing the object to be located in the screen, - recording of the descriptive data for each object that can be activated in said at least one database (4, 17, 20), - generating digitised phonetic data on the basis of the piece of textual data of each object that can be activated, - recording, in said at least one database (4, 17, 20), the digitised phonetic data of each object that can be activated, • and after capturing the vocal order: - digitising the vocal order received by the capture means for the control of an object that can be activated into a digital vocal order, - comparing said digital vocal order to said recorded digitised phonetic data, - identifying a piece of recorded digitised phonetic data that corresponds to the digital vocal order and recovering the piece of location data associated with said piece of digitised phonetic data identified, - activating the object that can be activated associated with the recovered location. • at each display of at least one graphic interface on the screen of the user terminal, identifying the objects that can be activated present in said at least one graphic interface thus displayed, and for each object that can be activated: - identifying a piece of descriptive data comprising a piece of location data and a piece of textual data of the object that can be activated, the piece of location data of the object that can be activated allowing the object to be located in the screen, - recording of the descriptive data for each object that can be activated in said at least one database (4, 17, 20), - generating digitised phonetic data on the basis of the piece of textual data of each object that can be activated, - recording, in said at least one database (4, 17, 20), the digitised phonetic data of each object that can be activated, - identifying a piece of descriptive data comprising a piece of location data and a piece of textual data of the object that can be activated, the piece of location data of the object that can be activated allowing the object to be located in the screen, - recording of the descriptive data for each object that can be activated in said at least one database (4, 17, 20), - generating digitised phonetic data on the basis of the piece of textual data of each object that can be activated, - recording, in said at least one database (4, 17, 20), the digitised phonetic data of each object that can be activated, • and after capturing the vocal order: - digitising the vocal order received by the capture means for the control of an object that can be activated into a digital vocal order, - comparing said digital vocal order to said recorded digitised phonetic data, - identifying a piece of recorded digitised phonetic data that corresponds to the digital vocal order and recovering the piece of location data associated with said piece of digitised phonetic data identified, - activating the object that can be activated associated with the recovered location. - digitising the vocal order received by the capture means for the control of an object that can be activated into a digital vocal order, - comparing said digital vocal order to said recorded digitised phonetic data, - identifying a piece of recorded digitised phonetic data that corresponds to the digital vocal order and recovering the piece of location data associated with said piece of digitised phonetic data identified, - activating the object that can be activated associated with the recovered location.
