Abstract
In embodiments, apparatuses, methods and storage media are described that are associated with alignment of closed captions. Video content (along with associated audio) may be analyzed to determine various times associated with speech in the video content. The video content may also be analyzed to determine various times associated with closed captions and/or subtitles in the video content. Likelihood values may be associated with the determined times. An alignment may be generated based on these determined times. Multiple techniques may be used, including linear interpolation, non-linear curve fitting, and/or speech recognition matching. Quality metrics may be determined for each of these techniques and then compared. An alignment for the closed captions may be selected from the potential alignments based on the quality metrics. The closed captions and/or subtitles may then be modified based on the selected alignment. Other embodiments may be described and claimed.
