Automatic filtering of TV contents using speech recognition and natural language
 Speech recognition and natural language parsing components are used to extract the meaning of the user's spoken input. The system stores a semantic representation of an electronic program guide, and the contents of the program guide can be mapped into the grammars used by the natural language parser. Thus, when the user wishes to navigate through the complex menu structure of the electronic program guide, he or she only needs to speak in natural language sentences. The system automatically filters the contents of the program guide and supplies the user with on-screen display or synthesized speech responses to the user's request.
