  • a database storing a list of content items organized by content title, each content title representing a database entry;

    a speech recognizer transcribing an utterance into a digital signal representing a textual statement;

    means for generating a grammar structure comprising various grammar paths, wherein every single word of each candidate content title that may be recognized is assigned to a single grammar path, said grammar structure further comprising a recursion loop by which every single word may be uttered any number of times and intermixed in order with any other word in said grammar structure;

    means for recognizing the utterance by the speech recognizer that uses said grammar;

    means for applying every single word of an output of said speech recognizer against each content title;
