Abstract:
Method, systems, and computer program products for synchronizing text with audio in a multimedia file, wherein the multimedia file is defined by a timeline having a start point and end point and respective points in time therebetween, wherein an N-gram analysis is used to compare each word of a closed-captioned text associated with the multimedia file with words generated by an automated speech recognition (ASR) analysis of the audio of the multimedia file to create an accurate, time-based metadata file in which each closed-captioned word is associated with a respective point on the timeline corresponding to the same point in time on the timeline in which the word is actually spoken in the audio and occurs within the video.
