Abstract

Claims (68)

1. An electronic device for providing information representing an operation state of a household electrical device, the electronic device comprising:

a memory storing a plurality of sound signals output from at least one household electrical device as a plurality of wake-up signals, and storing a plurality of pieces of operation state information, respectively, representing a plurality of operation states of the at least one household electrical device, the plurality of operation states being related to the plurality of sound signals, respectively; and

at least one processor operably coupled to the memory, the at least one processor configured to:

receive, from among the plurality of sound signals through a microphone, a first sound signal from a first household electrical device,

identify the first sound signal as a wake-up signal,

identify first operation state information corresponding to the first sound signal based on the plurality of pieces of operation state information, and

output, through an output interface, a notification message representing the first operation state information.

2. The electronic device of claim 1 , wherein:

the memory further stores at least one word uttered by a user as the wake-up signal; and

the at least one processor is further configured to:

receive, through the microphone, a voice input uttered by the user,

detect a wake-up voice from the voice input by identifying the at least one word from the voice input, and

in response to the wake-up voice being detected, perform a wake-up operation.

3. The electronic device of claim 2 , wherein the at least one processor is further configured to:

after performing the wake-up operation, transmit, through a communication interface, a second sound signal received from the first household electrical device to a server, and

receive, through the communication interface, second operation state information of the first household electrical device corresponding to the second sound signal from the server.

4. The electronic device of claim 1 , wherein the at least one processor is further configured to:

calculate similarities between the first sound signal and the plurality of sound signals stored in the memory,

determine, from among the plurality of sound signals, a sound signal having a greatest similarity as another sound signal corresponding to the first sound signal to identify the first operation state information, and

identify, from among the plurality of pieces of operation state information, the first operation state information corresponding to the determined sound signal to identify the first operation state information.

5. The electronic device of claim 1 , wherein the at least one processor is further configured to:

transmit, to a mobile terminal of a user through a communication interface, the first operation state information, the mobile terminal being connected to the electronic device through a wireless communication network, and

output, through the mobile terminal, the notification message representing the first operation state information.

6. The electronic device of claim 1 , wherein:

the memory further stores a plurality of pieces of follow-up operation information that is obtained in a connection with the plurality of pieces of operation state information; and

the at least one processor is further configured to:

identify first follow-up operation information related to the first operation state information, and

output the first follow-up operation information.

7. The electronic device of claim 1 , wherein the at least one processor is further configured to:

receive a new sound signal from a new household electrical device newly registered in a server and new operation state information corresponding to the new sound signal from the server through a communication interface, and

store device identification information of the new household electrical device, the new sound signal, and the new operation state information in the memory.

8. A method performed by an electronic device for providing information representing an operation state of a household electrical device, the method comprising:

receiving a first sound signal from a first household electrical device;

identifying the first sound signal as a wake-up signal;

identifying first operation state information corresponding to the first sound signal, based on a plurality of pieces of operation state information stored in memory;

outputting a notification message representing the first operation state information;

storing, in the memory, a plurality of sound signals output from at least one household electrical device as a plurality of wake-up signals; and

storing a plurality of pieces of operation state information, respectively, representing a plurality of operation states of the at least one household electrical device, the plurality of operation states being related to the plurality of sound signals, respectively.

9. The method of claim 8 , further comprising:

storing, in the memory, at least one word uttered by a user as the wake-up signal;

receiving a voice input uttered by the user;

detecting a wake-up voice from the voice input by identifying the at least one word from the voice input; and

in response to the wake-up voice being detected, performing a wake-up operation.

10. The method of claim 9 , further comprising:

after performing the wake-up operation, transmitting, to a server, a second sound signal received from the first household electrical device, and

receiving second operation state information of the first household electrical device corresponding to the second sound signal from the server.

11. The method of claim 8 , further comprising:

calculating similarities between the first sound signal and the plurality of sound signals stored in the memory;

determining, from among the plurality of sound signals, a sound signal having a greatest similarity as another sound signal corresponding to the first sound signal to identify the first operation state information; and

identifying, from among the plurality of pieces of operation state information, the first operation state information corresponding to the determined sound signal to identify the first operation state information.

12. The method of claim 8 , further comprising:

transmitting, to a mobile terminal of a user, the first operation state information, wherein the mobile terminal is connected to the electronic device through a wireless communication network; and

outputting, through the mobile terminal, the notification message representing the first operation state information.

13. The method of claim 8 , further comprising:

storing a plurality of pieces of follow-up operation information that is obtained in a connection with the plurality of pieces of operation state information;

identifying first follow-up operation information related to the first operation state information from the memory; and

outputting the first follow-up operation information.

14. The method of claim 8 , further comprising:

transmitting, to a server, a registration request including user account information and device identification information of a new household electrical device,

wherein the registration request includes a request to register the new household electrical device in the server based on a connection of the device identification information of the new household electrical device and the user account information.

15. A computer-readable recording medium embodying a computer program, the computer program comprising computer readable program code that when executed by at least one processor of an electronic device causes the at least one processor to:

receive a first sound signal from a first household electrical device;

identify the first sound signal as a wake-up signal;

identify first operation state information corresponding to the first sound signal, based on a plurality of pieces of operation state information stored in memory; and

output a notification message representing the first operation state information,

wherein, the medium is configured to:

store a plurality of sound signals output from at least one household electrical device as a plurality of wake-up signals, and

store a plurality of pieces of operation state information respectively representing a plurality of operation states of the at least one household electrical device, the plurality of operation states being related to the plurality of sound signals, respectively.
