Abstract

An electronic apparatus includes a communication interface, a microphone, and a processor configured to obtain a first expectation value for a first sound to be output from a first external electronic apparatus and a second expectation value for a second sound to be output from a second external electronic apparatus, control the communication interface to transmit a first sound output request signal to the first external electronic apparatus, obtain a first measurement value for the first sound, control the communication interface to transmit a second sound output request signal to the second external electronic apparatus, obtain a second measurement value for the second sound, and obtain a correction value for one or more of the first measurement value and the second measurement value based on the obtained first measurement value, the obtained second measurement value, the obtained first expectation value, and the obtained second expectation value.

First claim

What is claimed is:

1 . An electronic apparatus comprising:
a communication interface; a microphone; and a processor configured to be connected to the communication interface and the microphone to control the electronic apparatus, wherein the processor is configured to: obtain a first expectation value which is a predicted measurement value for a first sound to be output by a first external electronic apparatus based on first location information of the first external electronic apparatus and a second expectation value which is a predicted measurement value for a second sound to be output by a second external electronic apparatus based on second location information of the second external electronic apparatus; control the communication interface to transmit a first sound output request signal to the first external electronic apparatus to request the first sound to be output by the first external electronic apparatus, and based on the first sound being output from the first external electronic apparatus in response to the transmitted first sound output request signal, obtain a first measurement value for the first sound received through the microphone; control the communication interface to transmit a second sound output request signal to the second external electronic apparatus to request the second sound to be output by the second external electronic apparatus, and based on the second sound being output from the second external electronic apparatus in response to the transmitted second sound output request signal, obtain a second measurement value for the second sound received through the microphone; obtain a correction value for one or more of the obtained first measurement value of the received first sound and the obtained second measurement value of the received second sound obtained through the microphone based on the obtained first measurement value, the obtained second measurement value, the obtained first expectation value, and the obtained second expectation value; and based on the obtained first measurement value being not within a first threshold range based on the obtained first expectation value and the obtained second measurement value being within a second threshold range based on the obtained second expectation value, obtain a correction value for a measurement value of a sound output at a location within a threshold range based on a location corresponding to the first location information.

2 . The electronic apparatus according to claim 1 , wherein the processor is configured to:
based on the obtained first measurement value being more than the obtained first expectation value and the obtained second measurement value being more than the obtained second expectation value, obtain a negative correction value for reducing the one or more of the first measurement value and the second measurement value; and based on the obtained first measurement value being less than the obtained first expectation value and the obtained second measurement value being less than the obtained second expectation value, obtain a positive correction value for increasing the one or more of the first measurement value and the second measurement value.

3 . The electronic apparatus according to claim 1 , wherein the processor is further configured to, obtain the correction value for the measurement value of the sound output at the location within the threshold range based on the location corresponding to the first location information of the first external electronic apparatus based on a change of an apparatus which operates according to a wakeup command.

4 . The electronic apparatus according to claim 3 , wherein the processor is configured to:
based on the apparatus which operates according to the wakeup command being changed, obtain the correction value so that the apparatus which operates is restored; and based on the apparatus which operates according to the wakeup command being not changed, obtain the correction value as 0 or obtain the correction value within a range in which the apparatus which operates is not changed.

5 . The electronic apparatus according to claim 1 , wherein the processor is configured to:
receive a third measurement value for the second sound measured by the first external electronic apparatus and a third expectation value which is a predicted measurement value of the second sound by the first external electronic apparatus based on the second location information of the second external electronic apparatus from the first external electronic apparatus through the communication interface; and obtain the correction value for the measurement value of the sound obtained through the microphone based on the obtained first measurement value, the obtained second measurement value, the received third measurement value, the obtained first expectation value, the obtained second expectation value, and the received third expectation value.

6 . The electronic apparatus according to claim 5 , wherein the processor is configured to:
based on the first measurement value being not within a first threshold range based on the obtained first expectation value, the obtained second measurement value being not within a second threshold range based on the second expectation value, and the received third measurement value being within a third threshold range based on the received third expectation value, obtain the correction value for the measurement value of the sound obtained through the microphone.

7 . The electronic apparatus according to claim 5 , wherein the processor is configured to:
based on the first measurement value being not within a first threshold range based on the obtained first expectation value, the obtained second measurement value being within a second threshold range based on the obtained second expectation value, and the received third measurement value being within a third threshold range based on the received third expectation value, obtain a correction value for a measurement value of a sound output at a location within a threshold range based on a location corresponding to the first location information of the first external electronic apparatus based on a change of an apparatus which operates according to a wakeup command.

8 . The electronic apparatus according to claim 7 , wherein the processor is configured to:
based on the apparatus which operates according to the wakeup command being changed, obtain the correction value so that the apparatus which operates is restored; and based on the apparatus which operates according to the wakeup command being not changed, obtain the correction value as 0 or obtain the correction value within a range in which the apparatus which operates is not changed.

9 . The electronic apparatus according to claim 5 , wherein the processor is configured to control the communication interface to transmit a signal for requesting the third measurement value and the third expectation value based on hardware performance of the first external electronic apparatus to the first external electronic apparatus.

10 . The electronic apparatus according to claim 1 , wherein the processor is configured to:
control the communication interface to transmit the first expectation value request signal for the first external electronic apparatus and the second expectation value request signal for the second external electronic apparatus to an external server; and receive the first expectation value and the second expectation value from the external server through the communication interface.

11 . The electronic apparatus according to claim 1 , further comprising:
a memory configured to store first information for the first expectation
