The invention provides a voice noise reduction method and device, equipment, a storage medium and a program product, and relates to the technical field of computers, in particular to the technical field of voice. The specific implementation scheme is as follows: determining a to-be-denoised speech spectrum of a to-be-denoised speech signal; performing feature extraction on the to-be-denoised speech spectrum to obtain local speech spectrum features of the to-be-denoised speech spectrum; determining global speech spectrum features of the speech spectrum to be denoised according to the local speech spectrum features of the speech spectrum to be denoised; and determining a masking matrix of an original voice signal in a to-be-denoised voice signal according to the local voice spectrum feature and the global voice spectrum feature, and determining the original voice signal according to the to-be-denoised voice spectrum and the masking matrix. According to the embodiment of the invention, the voice noise reduction
