Claim 17:
18. The video sound-picture matching apparatus according to claim 16,
wherein determining the active segment includes:
determining a maximum value of a second forward duration according to the initial position of the start-stop mark and an end frame of the (j+1)th active segment, wherein the maximum value of the second forward duration is less than the maximum value of the first forward duration;
determining a second forward duration interval according to the maximum value of the first forward duration and the maximum value of the second forward duration;
scaling, in response to determining that the voice segment is within the second forward duration interval, a duration between the initial position of the start-stop mark and the start frame of the (j+1)th active segment according to a duration of the voice segment to obtain the active segment; and

the updating the initial position of the start-stop mark in response to determining that a condition for updating the position of the start-stop mark is met comprises:
meeting the condition for updating the position of the start-stop mark in response to determining that the voice segment is within the second forward duration interval; and
updating the initial position of the start-stop mark to a position corresponding to the start frame of the (j+1)th active segment.
