ABSTRACT:
The synchronization of an existing video to a new soundtrack is carried out through the phonetic analysis of the original soundtrack and the new soundtrack. Individual speech sounds, such as phones, are identified in the soundtrack for the original video recording, and the images corresponding thereto are stored. The new soundtrack is similarly analyzed to identify individual speech sounds, which are used to select the stored images and create a new video sequence. The sequence of images are then smoothly fitted to one another, to provide a video stream that is synchronized to the new soundtrack. This approach permits a given video sequence to be synchronized to any arbitrary utterance. Furthermore, the matching of the video images to the new speech sounds can be carried out in a highly automated manner, thereby reducing required manual effort.
