Abstract

The invention discloses a reverberation inhibition processing method and device. The method includes: acquiring to-be-processed sound data which are first sound data containing reverberation; processing the first sound data according to a similarity matrix to obtain preliminary reverberation inhibited second sound data, wherein the similarity matrix is obtained by pre-training; processing the second sound data on the basis of a Wavenet network model which is obtained by pre-training; acquiring output third sound data from the Wavenet network model. By the reverberation inhibition processing method and the device, problems of low accuracy and application scene limitation of reverberation inhibition algorithms in the correlation technique are solved.

Description

technical field [0001] The present application relates to the field of reverberation processing, in particular, to a processing method and device for reverberation suppression. Background technique [0002] When sound waves propagate indoors, they are reflected by obstacles such as walls, ceilings, and floors, and each reflection must be absorbed by obstacles. In this way, when the sound source stops sounding, the sound wave has to go through multiple reflections and absorptions in the room before disappearing. We feel that there are still several sound waves mixing for a period of time after the sound source stops sounding (the sound wave still remains after the sound source stops sounding in the room). The existing sound continuity phenomenon), this phenomenon is called reverberation. [0003] In a relatively closed indoor space, when the distance between the microphone and the sound source is long, such as using a hands-free phone, hearing aid, conference call, or when r...
