1. In an electronic system wherein features of spoken utterances are analyzed by a programmable pattern recognition system to provide recognition results, a method comprising the steps of:

  • coupling said electronic system to a source external to said electronic system;

    retrieving a first set of recognition programming information associated with a first recognition word set for said pattern recognition system from said external source;

    programming said pattern recognition system with said retrieved first set of recognition programming information to recognize a first set of words in the first recognition word set, wherein said pattern recognition system provides a first set of recognition results responsive to said first set of words;

    in response to the first set of recognition results, selectively retrieving from said external source a second set of recognition programming information associated with a second recognition word set for said pattern recognition system, wherein the selectively retrieved second set of recognition programming is selected based on the first set of recognition results; and

    reprogramming said pattern recognition system with said selectively retrieved second set of recognition programming information to recognize a second set of words in the second recognition word set, wherein said pattern recognition system provides a second set of recognition results responsive to the second set of words.
