Voice signal automatic gain control method and device, medium and equipment

The invention provides a voice signal automatic gain control method and device, a medium and equipment, and the method comprises the following steps: dividing an original voice signal into M frames of sub-voice signals, M being a positive integer; performing Fourier transform on the M frames of sub-voice signals to obtain M frames of frequency domain signals; calculating frequency spectrum energy corresponding to each frame of frequency domain signal; calculating a target gain corresponding to each frame of frequency domain signal based on the frequency spectrum energy corresponding to each frame of frequency domain signal; adjusting each frame of frequency domain signal based on the target gain to obtain adjusted M frames of frequency domain signals; and performing inverse Fourier transform on the adjusted M frames of frequency domain signals to obtain an adjusted voice signal. According to the invention, the problem of unstable voice signals caused by untimely gain coefficient adjustment is solved. 本发明提供了一种
