Abstract
A device is provided for authorizing the use of a selected function from among at least two functions of the device. The device includes storage for storing a function-specific voice pattern that is linked to the selected function, and a comparator for comparing an external input signal with the function-specific voice pattern. Also provided is a terminal unit for communicating with a device for authorizing use of a selected function of the device, and a communication system that includes a device for authorizing use of a selected function and a terminal unit for communicating with the device. Additionally, there are provided a method for giving a user authorization to use a selected function of a device, and a method for obtaining authorization to use a selected function of a device.

7. A terminal unit for communicating with a device for authorizing use of a selected function of the device, the device storing a function-specific voice pattern that is linked to the selected function, the terminal unit comprising:
-
a receiver interface for interfacing with the device;
a selector for allowing selection of a function as the selected function;
a voice message receiver for receiving a voice message;
a processor for processing the voice message; and
a transmitter for sending the processed message to the device for comparison with the voice pattern that is linked to the selected function. - View Dependent Claims (8, 9, 10, 11)

12. A communication system comprising:
-
a device for authorizing use of a selected function from among at least two functions of the device; and
a terminal unit for communicating with the device, wherein the device includes;
storage for storing a function-specific voice pattern that is linked to the selected function; and
a comparator for comparing the function-specific voice pattern with a processed message that is received from the terminal unit, and the terminal unit includes;
a receiver interface for interfacing with the device;
a selector for allowing selection of one of the functions of the device as the selected function;
a voice message recorder;
a processor for processing the recorded voice message; and
a transmitter for sending the processed message to the device.

13. A method for giving a user authorization to use a selected function of a device, the device storing a function-specific voice pattern that is linked to the selected function, the method comprising the steps of:
-
receiving the device at a receiving interface of a terminal unit;
receiving an identifier that is pronounced by the user, the identifier corresponding to the selected function;
processing the pronounced identifier in the terminal unit;
sending the processed identifier to the device for comparison with the voice pattern that is linked to the selected function; and
based on a result of the comparison by the device, receiving from the device either an authorization grant that allows use of the selected function, or an authorization denial that denies access to the selected function. - View Dependent Claims (14, 15, 16, 17, 18)

19. A method for obtaining authorization to use a selected function of a device, the device storing a function-specific voice pattern that is linked to the selected function, the method comprising the steps of:
-
interfacing the device with a terminal unit;
pronouncing an identifier that corresponds to the selected function; and
after recognition by the device of the voice pattern of the pronounced identifier, obtaining authorization to use the selected function. - View Dependent Claims (20, 21, 22)
