Abstract: Provided are a voice noise reduction method, an electronic device, and a non-transitory computer-readable storage medium. The specific implementation scheme includes determining a to-be-denoised voice spectrum of a to-be-denoised voice signal; performing feature extraction on the to-be-denoised voice spectrum to obtain a local voice spectral feature of the to-be-denoised voice spectrum; determining a global voice spectral feature of the to-be-denoised voice spectrum according to the local voice spectral feature of the to-be-denoised voice spectrum; and determining a masking matrix of an original voice signal in the to-be-denoised voice signal according to the local voice spectral feature and the global voice spectral feature, and determining the original voice signal according to the to-be-denoised voice spectrum and the masking matrix.
