The rapidly expanding voice recognition industry has so far shown a preference for grammar-based language modelling, despite the better overall performance of statistical language modelling. Given that the advantages of the grammar-based approach make it unlikely to be replaced as the primary solution in the near future, it is natural to wonder whether some combination of the two approaches may prove useful. Here, we describe an implemented system that uses statistical language modelling and a decision-tree classifier to provide the user with some feedback when grammar-based recognition fails. Users of this system had more successful interactions than did users of a control system.
