1. A method of making an integrated language model for a speech recognition engine, the method comprising:

  • using at least one processor and machine readable memory;

    identifying a first language model format for an upper-level language model component;

    identifying a plurality of text elements to be represented by a non-terminal in the upper-level language model component;

    generating the upper-level language model component including the non-terminal;

    identifying a second language model format for a lower-level language model component to be applied to the non-terminal of the upper-level language model component; and

    generating the lower-level language model component;

    wherein generating the upper-level language model component includes modifying an existing language model; and

    wherein identifying the plurality of text elements to be represented by the non-terminal in the upper-level language model component includes applying an automatic text element replacement criterion to the existing language model.
