Moving image playback apparatus, moving image playback method, and computer program thereof with determining of first voice period which represents a human utterance period and second voice period other than the first voice period

摘要

In a moving image playback apparatus, periods A which represent human utterance periods, and other periods B are determined on the basis of sub-information contained in moving image data. Based on the moving image data, periods A undergo high-speed moving image playback with playback voice within the speed range from a normal speed to a predetermined speed (e.g., 1.5 to 2 times of the normal speed) at which the user can recognize playback contents, while periods B undergo high-speed moving image playback with at least playback voice in a small tone volume or silent high-speed moving image playback at a speed (e.g., 5 to 10 times of the normal speed) higher than the predetermined speed. During the playback, the moving image playback speeds can be adjusted in accordance with user attribute information registered in a user profile (14).
