METHOD AND APPARATUS FOR PROCESSING SOUND SIGNALS, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/227932
Kind Code:
A1
Abstract:
The embodiments of the present disclosure disclose a method and apparatus for processing sound signals, and an electronic device. A specific embodiment of the method comprises: on the basis of a far-end signal from a second terminal, performing linear filtering on a microphone signal spectrum of a microphone signal acquired by a first terminal, and generating a linearly filtered signal spectrum, the microphone signal being a sound signal acquired after the far-end signal is played back; on the basis of a far-end signal spectrum, the microphone signal spectrum, and the linearly filtered signal spectrum, determining an echo signal masking value of at least one frequency point in the linearly filtered signal spectrum; using the determined at least one echo signal masking value to mask an overlaid echo signal spectrum in the linearly filtered signal spectrum, and generating a target near-end signal spectrum; and converting the target near-end signal spectrum into a target near-end signal. Therefore, by removing a linear echo signal and a nonlinear echo signal contained in a microphone signal, the quality of a voice call between a first terminal and a second terminal is improved.
