Claim 12:
13. The video sound-picture matching method according to claim 8, further comprising:
acquiring, in response to determining that the voice segment is not within the target reverse duration interval and the duration of the voice segment is greater than the maximum value of the first reverse duration, a qth active segment from the image sequence, wherein q is an integer greater than or equal to 1 and less than or equal to N;
determining a minimum value of a third reverse duration according to the maximum scaling, the initial position of the start-stop mark, and an end frame of the qth active segment;
determining a maximum value of the third reverse duration according to the minimum scaling, the initial position of the start-stop mark, and a start frame of a (q−1)th active segment;
determining a fourth reverse duration interval according to the minimum value of the third reverse duration and the maximum value of the third reverse duration;
determining, in response to determining that the voice segment is within the fourth reverse duration interval, a duration of the active segment according to the initial position of the start-stop mark, the maximum scaling, and the end frame of the qth active segment; and
dividing, according to the duration of the active segment, the voice segment into a third voice segment and a fourth voice segment, wherein a duration of the third voice segment is consistent with the duration of the active segment, and the fourth voice segment is used for matching a corresponding action segment according to the updated initial position of the start-stop mark; 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 fourth forward duration interval; and
updating the initial position of the start-stop mark to a position corresponding to the end frame of the qth active segment.
