Abstract: A voice awakening method and apparatus, a device, and a medium are provided. The voice awakening method includes: collecting a voice signal by using a microphone array (S201); separately performing denoising processing on the voice signal by using N beamforming denoising algorithms to obtain N denoising signals, where each beamforming denoising algorithm corresponds to one of N areas, different beamforming denoising algorithms correspond to different areas, a union set of the N areas covers a signal collection area of the microphone array, and N is a positive integer greater than 1 (S202); and performing voice awakening by using an awakening engine based on at least one of the N denoising signals (S203). The method can maximize denoising performance of the denoising algorithms and can cancel an echo outside a beam to enhance echo cancellation performance, featuring a relatively high awakening rate and recognition rate. In addition, the method is easy to implement and popularize.
