Title:
APPARATUS AND METHOD FOR GENERATING AUDIO SIGNAL WITH NOISE ATTENUATED ON BASIS OF PHASE CHANGE RATE ACCORDING TO CHANGE IN FREQUENCY OF AUDIO SIGNAL
Document Type and Number:
WIPO Patent Application WO/2019/156339
Kind Code:
A1
Abstract:
Disclosed is an electronic apparatus. Various other embodiments are also possible which are known from the specification. The electronic apparatus comprises: a plurality of input devices for receiving a plurality of input signals including a speech signal and a noise signal; and a processor electrically connected to the input devices, wherein the processor may be configured to determine signal to noise ratio (SNR) values for the plurality of input signals for each frequency band, determine a first parameter indicative of a change in phase relative to the frequency of the plurality of input signals in a first frequency band in which an SNR value is greater than or equal to a specified threshold value, determine, on the basis of the first parameter, a second parameter indicative of a change in phase relative to the frequency of the plurality of input signals in a second frequency band in which the SNR value is less than the threshold value, and perform beamforming on the plurality of input signals on the basis of the first parameter and the second parameter.
