When the user says "i want to play XX song", "open the accompaniment of XX music", or "the accompaniment of XX song", etc., the accompaniment, i.e., the second audio, can be opened while stopping playing the first audio. The performance action of the virtual user is preserved, and the accompaniment is matched according to the rhythm of the user performance.
In this embodiment, when the playing effect of the user is poor or the playing level of the user is low, the playing sound of the user may not be played, and only the second audio selected by the user may be played. Therefore, even if the playing effect of the user is poor, the video matched with the hand motion of the user and the played second audio can be recorded, and the playing effect is optimized.
Optionally, the first action information includes amplitude information and frequency information of the action of the first user;
