A speech noise reduction processing method, an apparatus, a computer device and a storage medium. The method comprises: responsive to a distance between a speech collection device and a target object being detected to reach a preset value, acquiring a noisy speech signal collected by the speech collection device and performing frequency division processing on the noisy speech signal to obtain a low-frequency band signal; acquiring an amplitude spectrum and a phase spectrum of the low-frequency band signal; acquiring a modulation domain signal corresponding to the amplitude spectrum; performing spectral subtraction to obtain a noise-reduced modulation domain amplitude spectrum; compensating the modulation domain phase spectrum to obtain the compensated modulation domain phase spectrum; and obtaining a noise-reduced low-frequency band signal based on the compensated modulation domain phase spectrum, the noise-reduced modulation domain amplitude spectrum and the phase spectrum of the low-frequency band signal.
