Voice signal processing method and device, electronic equipment and nonvolatile storage medium

The invention discloses a voice signal processing method and device, electronic equipment and a nonvolatile storage medium, and is applied to the field of artificial intelligence. The method comprises the steps that a voice environment matching degree recognition model used for recognizing whether a target voice enhancement algorithm is suitable for an environment where voice to be enhanced is located or not is constructed in advance, and the recognition model is obtained through training based on a voice enhancement signal training data set containing multiple voice quality features; and obtaining a target voice quality feature of the voice enhancement signal processed by the target voice enhancement algorithm and a target environment feature of a target environment where the to-be-enhanced voice is located. Inputting the target voice quality features and the target environment features into a voice environment matching degree recognition model; and under the condition that the voice environment matching deg
