Automated Estimation of Time Codes for Captioning Digital Media

PST4 Poster Sessions Track

Plaster Student Union Ballroom


The process of creating synchronized captions for media is time- and labor-intensive. Algorithms were developed to automate part of that process by estimating the timing of captions for Web-based audio and video files using plain-text transcripts and their corresponding audio recordings. In the conducted study, the algorithm accurately estimated the timing of 96% of the captions within 0.5 seconds. The resulting estimations were then retrieved and inserted into templates for SMIL for Real Player, SMIL for QuickTime, SAMI for Windows Media Player, and XML captions for Flash.

This presentation will include a demonstration of the Web application developed using the study's results.
