1. A computer-implemented method of generating a grammar for recognizing headings in a speech recognition system comprising:

  • determining that said at least one heading section is to be presented to a user;

    based on the determination, automatically identifying, within a data store, at least one heading selection associated with a content item, wherein each of said at least one heading selection is able to be used as a selection item for identifying the content item through a speech interface;

    automatically extracting at least a first word from each said identified heading selection, wherein said extracted at least a first word includes “

    n”

    words of the heading section, and wherein “

    n”

    is less than the total number of words in the heading selection;

    automatically generating a heading grammar by including each said extracted word of said identified heading selections within said heading grammar;

    presenting said identified headings to the user; and

    speech recognizing a spoken user selection using said heading grammar.
