Abstract

The present disclosure relates to a server and a system including the same. The server according to an embodiment of the present disclosure includes: a communicator configured to perform communication through a network; a storage configured to store data on at least one predetermined word; and a controller configured to: upon receiving an input signal, including data on speech, from a first electronic device through the communicator, determine whether a last part of the speech corresponds to any one of the at least one predetermined word; in response to there being a word corresponding to the last part of the speech among the at least one predetermined word, transmit a first response signal, including data on a response to the speech and data on at least one additional query, to the first electronic device through the communicator; and in response to there being no word corresponding to the last part of the speech among the at least one predetermined word, transmit a second response signal, including data on a response to the speech, to the first electronic device through the communicator. Various other embodiments are also possible.

Dependent claims

A server, comprising:

a communicator configured to perform communication through a network;
a storage configured to store data on at least one predetermined word and data on an operation history of each of at least one electronic device;
and
a controller configured to:
upon receiving an input signal, including data on speech, from a first electronic device through the communicator, determine whether a last part of the speech corresponds to any one of the at least one predetermined word;
in response to there being a word corresponding to the last part of the speech among the at least one predetermined word, transmit a first response signal, including data on a response to the speech and data on at least one additional query, to the first electronic device through the communicator;
and
in response to there being no word corresponding to the last part of the speech among the at least one predetermined word, transmit a second response signal, including data on a response to the speech, to the first electronic device through the communicator,
wherein, in response to at least one first operation history associated with the response to the speech being present in the data on the operation history of the first electronic device, the controller is configured to generate a first additional query about the first electronic device based on the first operation history, and
wherein the first operation history corresponds to an operation performed in the first electronic device in relation to the response before the speech is input to the first electronic device.

7 more elements

A system comprising at least one electronic device and a server including a storage configured to store data on at least one predetermined word and data on an operation history of each of the at least one electronic device,

wherein among the at least one electronic device, a first electronic device is configured to:
upon receiving speech, transmit an input signal including data on the speech to the server;
and
upon receiving a response signal responsive to the input signal from the server, output speech according to the received response signal,
wherein the server is configured to:
upon receiving the input signal from the first electronic device, determine whether a last part of the speech included in the input signal corresponds to any one of the at least one predetermined word;
in response to there being a word corresponding to the last part of the speech among the at least one predetermined word, transmit a first response signal, including data on a response to the speech and data on at least one additional query, to the first electronic device;
and
in response to there being no word corresponding to the last part of the speech among the at least one predetermined word, transmit a second response signal, including data on a response to the speech, to the first electronic device,
wherein, in response to at least one first operation history associated with the response to the speech being present in the data on the operation history of the first electronic device, the server is further configured to generate a first additional query about the first electronic device based on the first operation history, and
wherein the first operation history corresponds to an operation performed in the first electronic device in relation to the response before the speech is input to the first electronic device.
