Abstract

The embodiment of the invention relates to a voice signal de-noising and pickup processing method and apparatus, and a refrigerator. The method comprises: a microphone array collects voice signals of a current environment; time synchronization is carried out on the collected multi-path voice signals; and weighting and summation are carried out on the synchronized multi-path voice signals to obtain voice signals after denoising. With a self-filtering way, the bandwidth is reset, so that the voice quality can be improved; the voice characteristic is protected from being changed based on a weight adding way; the echo can be eliminated effectively; the signal to noise ratio can increase; and the area of interest can be enhanced by using the direction selection characteristic.
