Claim 0:
1. A video sound-picture matching method, performed by a computing device, the method comprising:
acquiring a voice sequence, the voice sequence including M voice segments, and M being an integer greater than or equal to 1;
acquiring a voice segment from the voice sequence, the voice segment being to any voice segment in the voice sequence;
acquiring an initial position of a start-stop mark and a moving direction of the start-stop mark from an image sequence, the image sequence including N active segments, each active segment including an action picture of an object, the initial position of the start-stop mark being a start frame of the active segment or an end frame of the active segment and being less than or equal to a start frame of a jth active segment, N being an integer greater than or equal to 1, and j being an integer greater than or equal to 1 and less than or equal to (N+1);
determining an active segment according to the initial position of the start-stop mark, the moving direction of the start-stop mark in a forward direction, and the voice segment, comprising:
determining a minimum value of a first forward duration according to a minimum scaling, the initial position of the start-stop mark, and an end frame of the jth active segment;
determining a maximum value of the first forward duration according to a maximum scaling, the initial position of the start-stop mark, and a start frame of the (j+1)th active segment;
determining a target forward duration interval according to the minimum value of the first forward duration and the maximum value of the first forward duration; and
determining, in response to determining that the voice segment is within the target forward duration interval, the active segment according to at least one of the jth active segment and the (j+1)th active segment; and

synthesizing the voice segment and the active segment to obtain a video segment, the video segment including the action picture of the object and a voice of the object.
