Abstract

A method for controlling operation of an appliance by a user through voice control includes at least the steps of: detecting, by the appliance, a control action performed by the user on the appliance; activating a voice control system by the appliance; capturing, by the voice control system, a voice input from the user as a captured voice input; recognizing, by the voice control system, a piece of information and/or an instruction in the captured voice input from the user as a recognized information and/or instruction; and executing, by the voice control system, a user control action on the appliance in accordance with the recognized information and/or instruction.

First claim

What is claimed is:

1 . A method for controlling operation of an appliance by a user through voice control, the method comprising at least the steps of:
detecting, by the appliance, a control action performed by the user on the appliance; activating a voice control system by the appliance; capturing, by the voice control system, a voice input from the user as a captured voice input; recognizing, by the voice control system, a piece of information and/or an instruction in the captured voice input from the user as a recognized information and/or instruction; and executing, by the voice control system, a user control action on the appliance in accordance with the recognized information and/or instruction.

2 . The method as recited in claim 1 , wherein the control action performed by the user on the appliance comprises an additional operation that goes beyond a normal intended use of the appliance, or
wherein the control action performed by the user on the appliance is an operation that is part of a normal intended use of the appliance.

3 . The method as recited in claim 1 , wherein the control action performed by the user on the appliance is performed in a contact-based or contactless manner.

4 . The method as recited in claim 1 , wherein the control action performed by the user on the appliance comprises an approach of the user to the appliance.

5 . The method as recited in claim 1 , wherein detection of a control action performed by the user on the appliance is accomplished by a modular and/or energy-autonomous sensor.

6 . The method as recited in claim 1 , further comprising:
after activating the voice control system, indicating, by the appliance, the activated voice control system.

7 . The method as recited in claim 1 , further comprising:
after capturing a voice input from the user, outputting feedback in response to the captured voice input from the user.

8 . The method as recited in claim 1 , wherein execution, by the voice control system, of a user control action on the appliance occurs after a predetermined time delay.

9 . The method as recited in claim 1 , further comprising:
after capturing a voice input from the user, outputting information and/or an instruction to another device.

10 . The method as recited in claim 1 , further comprising:
after executing, by the voice control system, a user control action on the appliance, deactivating, by the appliance, the activated voice control system.

11 . The method as recited in claim 1 , further comprising:
after executing, by the voice control, a user control action on the appliance, maintaining the activated voice control system for a predetermined period of time.

12 . The method as recited in claim 1 , wherein the voice control system forms part of the appliance.

13 . The method as recited in claim 1 , wherein the voice control system is independent of the appliance.

14 . The method as recited in claim 1 , wherein the appliance comprises a household appliance.

15 . The method as recited in claim 1 , wherein via the activating, a plurality of voice control systems are activated by the appliance, and
wherein via the capturing step, a voice input from the user is captured by at least one voice control system of the plurality of voice control systems.

16 . The method as recited in claim 15 , wherein via the capturing, a plurality of voice inputs from a plurality of users are in each case captured by at least one voice control system, and
wherein via the recognizing the piece of information and/or the instruction in the captured voice inputs from the users, the information and/or instruction is in each case recognized as such or discarded by at least one voice control system.

17 . The method as recited in claim 16 , wherein the captured voice inputs of one voice control system are prioritized over the captured voice inputs of the at least one further voice control system.

18 . The method as recited in claim 1 , wherein a plurality of appliances and/or a plurality of voice control systems are present, with one or more appliances being associated with a voice control system.

19 . The method as recited in claim 18 , wherein distance detection is performed to detect a distance between at least one of the associated appliances and the voice control system, and
wherein at least activating of the voice control system by the appliance occurs only if the associated appliances and voice control systems are detected to be within a predetermined distance from one another.

20 . The method as recited in claim 1 , wherein distance detection is performed to detect a distance between at least one appliance and a plurality of voice control systems, and
wherein at least the activating of the voice control system by the appliance occurs only for the voice control system that has the least distance from the activated appliance.

21 . The method as recited in claim 18 , wherein the associated voice control system determines a signal strength of a signal emitted by the appliance, or
wherein the appliance determines a signal strength of a signal emitted by the associated voice control system, at least the activating of the voice control system by the appliance occurring only if the determined signal strength is equal to or greater than a predetermined value.

22 . The method as recited in claim 18 , wherein the appliance determines a signal strength of one or more signals emitted by a plurality of voice control systems, and
wherein at least the activating of the voice control system by the appliance occurs only for the voice control system that has a highest signal relative to a known output signal strength of the signal of the voice control system.

23 . The method as recited in claim 19 , wherein the appliance transmits at least one additional piece of information to the associated voice control system, and
wherein at least the activating of the voice control system by the appliance occurs only if the transmitted additional piece of information is captured by the associated voice control system.

24 . An appliance for carrying out the method according to claim 1 , the appliance being configured to detect the control action performed by the user on the appliance and to activate the voice control system,
wherein the voice control system is configured to capture the voice input from the user as the captured voice input, recognize the piece of information and/or the instruction in the captured voice input from the user as the recognized information and/or instruction, and execute the user control action on the appliance in accordance with the recognized information and/or instruction.

25 . The method as recited in claim 20 , wherein at least the activating of the voice control system by the appliance occurs only for the voice control system that does not exceed a maximum distance.

26 . The appliance as recited in claim 24 , wherein the appliance comprises a household appliance.
