Classification: CPC G  H | IPC G  H

Claim 7:
8. A method of controlling an electronic apparatus storing a first threshold value and a second threshold value corresponding to a receiving direction of a wake-up word, the method comprising:
identifying a receiving direction of a sound based on a sound received through the sound receiver;
based on a similarity between sound data obtained in response to a received sound and the wake-up word being greater than or equal to the first threshold value corresponding to the identified receiving direction, performing voice recognition for a subsequent sound; and
based on the similarity being less than the first threshold value and greater than or equal to the second threshold value, changing the first threshold value,
wherein the changing the first threshold value comprises, based on the similarity being less than the first threshold value and greater than or equal to the second threshold value, changing the first threshold value to increase by a specified ratio,
wherein the first threshold value and a second threshold value respectively correspond to a first receiving direction and a second receiving direction,
wherein the changing the first threshold value comprises, based on the identified receiving direction being the first receiving direction, changing a first threshold value corresponding to the first receiving direction and maintaining a first threshold value corresponding to the second receiving direction,
wherein the first threshold value is a similarity to identify whether the sound is the wake-up word, and
wherein the second threshold value is a similarity to identify whether the sound is a particular noise source.
