System and computerized method for subtitles synchronization of audiovisual content using the human voice detection for synchronization

A method for synchronization of subtitles and human voice segments of an audiovisual content comprises:

• gathering a plurality of audio segments of the audiovisual content;
• gathering a plurality of subtitles of the audiovisual content;
• generating a list of possible start offsets and end offsets for the plurality of audio segments and the plurality of subtitles;
• determine a best cost and a plurality of factor values by performing a calculation on each of the start offsets and end offsets of the plurality of audio segments and the plurality of subtitles;
• generating a notification that no match has been found upon determination that the best cost is not less than a value defined as infinity;
• generating a notification that no correction is necessary upon determination that the plurality of factors have each a predetermined value and that the best cost is less than a value defined as infinity;
• and
• performing a subtitle offset correction upon determination that the plurality of factors do not have each a predetermined value and that the best cost is less than a value defined as infinity.
