A speech recognition method includes receiving a first multi-channel audio signal; obtaining at least one of a speech signal characteristic or a noise signal characteristic for at least one frequency band of frequency bands corresponding to channel audio signals included in the first multi-channel audio signal; generating a signal with an enhanced speech component by performing beamforming on the first multi-channel audio signal based on the speech signal characteristic, a speech signal characteristic obtained for a previous frame that was obtained before a certain time that the first multi-channel audio signal was obtained, and the noise signal characteristic; determining whether the enhanced speech component includes a wake word; and based on determining that the enhanced speech component includes the wake word: activating a speech recognition operation based on the signal with the enhanced speech component.

Method and apparatus for performing speech recognition with wake on voice (WoV)

A method, performed by an electronic device, of identifying location information of an external includes: obtaining map information including location information for each time interval of a mobile device based on the mobile device moving while generating noise near the external device; obtaining audio signal information about an audio signal including the noise generated by the mobile device, the audio signal being collected by a microphone of the external device; identifying, from the audio signal information, a time point at which a noise level of the noise generated by the mobile device is highest; obtaining, from the map information, location information of the mobile device corresponding to the identified time point; and identifying the location information of the external device based on the obtained location information of the mobile device.
