The invention discloses a voice wake-up processing method and device, a storage medium and electronic equipment, and relates to the technical field of audio processing, and the method comprises the steps: obtaining a to-be-processed voice signal; performing adaptive filtering echo cancellation processing on the to-be-processed voice signal to obtain an error signal; performing echo cancellation nonlinear post-processing based on the post-processing input signal and the voice signal to be processed by adopting a nonlinear post-processing network to obtain an echo cancellation signal; a wake-up network is adopted, wake-up detection processing is performed based on an echo cancellation signal, a nonlinear post-processing network and the wake-up network are obtained by joint adversarial training, and in the adversarial training, the nonlinear post-processing network is used as a generator and the wake-up network is used as a discriminator. The target of the adversarial training is that the identification accuracy
