One example method is applied to an electronic device, where the electronic device includes a microphone array and a camera. The example method includes performing sound source localization on a first audio signal obtained by using the microphone array, to obtain sound source direction information. A first video obtained by using the camera is processed to obtain user direction information. A target sound source direction is determined based on the sound source direction information and the user direction information. A user lip video is obtained in the target sound source direction by using the camera. A second audio signal is obtained by using the microphone array. A third audio signal is obtained based on the second audio signal and the user lip video by using a voice quality enhancement model.
