The invention discloses an audio de-reverberation method and device, equipment and a storage medium, and belongs to the technical field of computers. The method comprises the following steps: determining an extended audio segment according to a preset extended frame number; inputting the spectrum data of each audio frame in the extended audio segment into a time sequence attention network to obtain a weight value corresponding to the spectrum data of each reference audio frame; multiplying the spectrum data of each reference audio frame by the corresponding weight value to obtain the adjusted spectrum data of each reference audio frame; and according to the adjusted spectrum data of each reference audio frame, the spectrum data of the target audio frame and the de-reverberation network, determining audio data of the target audio frame after de-reverberation processing. By adopting the method and the device, the correlation between the reverberation generated in the target audio frame and the reference audio frame is considered, the reference audio frame and the target audio frame are comprehensively considered, relatively accurate reverberation removal processing is realized on the target audio frame, and the accuracy of the reverberation removal processing is improved.
Description
technical field [0001] The present application relates to the field of computer technology, and in particular to an audio reverberation method, device, equipment and storage medium. Background technique [0002] In the fields of speech recognition and audio processing, reverberation is an important factor that interferes with audio clarity. For example, when speaking in a room at a certain distance from the microphone, due to the reflection of audio signals by objects and walls in the room, so The audio signal received by the microphone is a collection of many delayed and attenuated original audio signals, resulting in reverberation in the received audio signal, which seriously reduces the clarity of the audio. [0003] The current method of de-reverberation processing of audio is: respectively input the spectral data of each audio frame doped with reverberation into the de-reverberation network, so as to obtain the spectrum of the audio frame after de-reverberation processi...
