Abstract

The invention discloses a sound signal processing method, device and interactive intelligent equipment, which are applied in the field of signal processing. Wherein, the method includes: receiving the original sound signal; performing first filtering processing on the original sound signal based on a nonlinear filter to obtain a first processing result, wherein the first filtering processing is used to suppress reverberation on the original sound signal; The first processing result updates the coefficient of the linear adaptive filter; the linear adaptive filter based on the updated coefficient performs the second filtering process on the first processing result, and outputs the final processing result of the original sound signal, wherein the second filtering process uses For performing reverberation suppression on the first processing result. The invention solves the technical problem in the prior art that it is difficult to maintain a relatively low algorithm complexity while obtaining a better suppression effect when reverberation suppression is performed on the sound signal, and achieves the reduction of execution complexity while ensuring the suppression effect the goal of.

Description

technical field [0001] The present invention relates to the field of signal processing, in particular to a sound signal processing method, device and interactive intelligent equipment. Background technique [0002] With the development of multimedia equipment, the requirements for the transmission of sound information are getting higher and higher. For example, in scenarios such as teleconferencing and distance teaching, while disseminating image information, it is also necessary to clearly disseminate sound information. However, in the process of sound propagation, reverberation will be generated after multiple reflections, which will cause reverberation signals to be included in the sound information received by the receiving end. The reverberation signal will damage the quality of the original signal, so the reverberation signal needs to be suppressed to improve the sound quality. [0003] At present, the receiving end of the sound signal will suppress the reverberation...
