Self-adaptive noise reduction method and device and computer equipment

The invention provides a self-adaptive noise reduction method and device and computer equipment. The method comprises the following steps: acquiring voice data; wherein the voice data at least carries background sound information; analyzing the voice data to obtain the background sound information; inputting the background sound information into a classification model for classification to obtain a corresponding classification result; wherein the classification model is a pre-trained neural network model; obtaining identification information corresponding to the classification result; detecting whether a target identification field which is the same as the identification information exists in a database or not; if yes, determining a corresponding target noise reduction model according to the target identification field; and based on the target noise reduction model, performing noise reduction processing on the voice data. According to the invention, based on different backgrounds in the voice data, the corres
