audio signal noise reduction method and device, readable medium and electronic equipment

The invention relates to an audio signal noise reduction method and device, a readable medium and electronic equipment. The method comprises the steps: obtaining a noise-containing audio signal, inputting the noise-containing audio signal into a pre-trained deep learning model, determining a target audio signal according to the output result of the deep learning model, and obtaining the audio signal without noise after the noise is removed from the audio signal, wherein the deep learning model comprises at least one long short-term memory network in a trained progressive deep neural network, the progressive deep neural network comprises a plurality of long short-term memory networks, under the condition that an audio training sample is respectively input into a plurality of long short-term memory networks, output results of the plurality of long short-term memory networks respectively correspond to noise reduction audio samples obtained by improving different signal to noise ratios of the audio training sampl
