Script recognition using speech recognition

Abstract

Abstract Script recognition using speech recognition for use in editing of video or film clips uses preferably a grammar based speech recognition engine. A script file and audio dialog file are input a speech recognition system, and the script file is processed to generate a grammar file, which in turn is reduced to a binary context file compatible with a specific speech recognition engine. The script file and audio file are used to define variable parameters for the speech recognition engine. The audio file is broken up into utterances which are processed by the speech recognition engine according to the variable parameters and the context file. The best "guess" from the speech recognition engine is fitted to the script file to determine a match. Mismatched utterances are fed back to the utterance determining step to determine a new search point. With a match the audio file is marked with the corresponding location in the script or the script file is time marked with the corresponding video clip time code. Video or film clips may then be accessed for editing by indicating a place in the script or the dialog.
