Abstract
This invention is directed to the selection of superwords based on a criterion relevant to speech recognition and understanding. Superwords are used to refer to those word combinations which are so often spoken that they are recognized as units or should have models to reflect them in the language model. The selected superwords are placed in a lexicon along with selected meaningful phrases. The lexicon is then used by a speech recognizer to improve recognition of input speech utterances for the proper routing of a user's task objectives.
