Zusammenfassung:The invention discloses a voice signal extraction method and device, electronic equipment and a computer readable medium, and the method is applied to the electronic equipment, and the method comprises the steps: collecting a first audio signal based on an audio collection module of the electronic equipment, and the first audio signal comprises a target audio signal and an interference audio signal; determining a first covariance matrix corresponding to the target audio signal and a second covariance matrix corresponding to the interference audio signal; determining a target filtering parameter based on the first covariance matrix and the second covariance matrix; and filtering the first audio signal based on the target filtering parameter, and extracting the target audio signal in the first audio signal. According to the method, the target filtering parameter is determined through the first covariance matrix and the second covariance matrix, so that the target audio signal in the first audio signal is extrac
