Abstract

The invention discloses an elimination method and device of echo, a storage medium and an electronic device. The elimination method comprises the steps that first audio data received by first equipment are obtained; non-linear echo data corresponding to the first audio data are estimated according to the non-linear echo characteristic information, linear echo data corresponding to the first audio data is estimated, and wherein the non-linear echo characteristic information is used for indicating non-linear echo characteristics of the first equipment; a first audio signal and a second audio signal are acquired by the first equipment to obtain second audio data; the non-linear echo data and the linear echo data are eliminated from the second audio data, and target audio data is obtained; and the target audio data is transmitted to second equipment transmitting the first audio data. According to the elimination method, the technical problem of low efficiency of eliminating the echo is solved.

Description

technical field [0001] The present invention relates to the field of computers, in particular to an echo cancellation method, device, storage medium and electronic device. Background technique [0002] With the development of technology, people can make voice calls through a variety of small mobile terminal devices, including: mobile phones, laptops, smart speakers, smart watches, etc. The miniaturization and diversification of communication devices bring challenges to the design of echo cancellers, which are indispensable in voice communication systems. The current echo canceller can only predict the linear part of the echo path. For the nonlinear echo, the nonlinear echo filter is mainly designed through empirical values. The miniaturization and diversification of communication equipment brings two main problems: First, the nonlinear echo component increases, which poses challenges to the echo suppression capability of the echo canceller. Secondly, the non-linear echo co...
