Abstract
Automatically searching for one or more matches to a search string includes accessing a first part and a second part of a search string. A first search space is searched for a match for the first part of the search string, and a second search space is limited based on a result of searching the first search space. The limited second search space is searched for a match for the second part of the search string. Various approaches are described for structuring a grammar of a voice recognition engine to allow efficient, quick recognition, and to enhance recognition by limiting the amount of the grammar that is searched, thus minimizing the incidence of misrecognition. Search strings can be recognized and searched using a multi-cluster approach. Recognition and searching can also be performed using a multi-level, multi-parameter cascade approach. Approaches can also be applied to recognition of other modes of input.
