Abstract
The production of closed captions is an important but expensive process in video broadcasting. We propose a method to generate highly accurate off-line captions efficiently. Our system uses text alignment to synchronize program transcripts obtained for a video program with text produced by an automatic speech recognition (ASR) system. We will also describe the accuracy in both closed-caption text and the ASR output for a number of news programs and provide a detailed analysis of the errors that occur.
