CONTROL AND CONFIGURATION OF A SPEECH RECOGNIZER BY WORDSPOTTING
First Claim
1. A method for processing a speech source comprising:
- applying a wordspotting procedure to the speech source according to a set of specified queries to produce a set of putative hits corresponding to the queries;
computing a speech recognition specification from the produced putative hits; and
applying a speech recognition procedure to the speech source according the speech recognition specification to produce a transcription of at least some of the speech source.

Abstract
A wordspotting system is applied to a speech source in a preliminary processing phase. The putative hits corresponding to queries (e.g., keywords, key phrases, or more complex queries that may include Boolean expressions and proximity operators) are used to control a speech recognizer. The control can include one or more of application of a time specification that is determined from the putative hits for selecting an interval of the speech source to which to apply the speech recognizer; application of a grammar specification determined from the putative hits that is used by the speech recognizer, and application of a specification of a lattice or pruning specification that is used by the recognizer to limit or guide the recognizer in recognition of the speech source.

14. A system for processing a speech source comprising:
-
a wordspotting component for processing the speech source according to a set of specified queries to produce a set of putative hits corresponding to the queries; a control component for computing a speech recognition specifications from the produced putative hits; and a speech recognizer for processing the speech source according the speech recognition specification to produce a transcription of at least some of the speech source.
