Technology Application

Video Captioning This software is available for licensing.

Detailed Technology Description

Researchers at the University of California, Santa Barbara have developed a novel software that automatically and accurately synchronizes pre-segmented transcripts with corresponding videos. The system first creates a new speech recognition system (SRS) language model for each video, which greatly improves the accuracy in identifying spoken words. It then uses recognized time-stamped words to time stamp aligned captions. Finally, unrecognized words are given estimated time-stamps along with a reported error bound, giving the content creator a measure of the caption accuracy. This software is applicable to video captioning.

Background
