SPEECH RECOGNITION UTILIZING A DYNAMIC SET OF GRAMMAR ELEMENTS
First Claim
Patent Images
1. A speech recognition system comprising:
- at least one memory configured to store a plurality of grammar elements;
at least one input device configured to receive a speech input; and
at least one processor configured to (i) identify at least one item of contextual information and (ii) determine, based at least in part upon the contextual information, a correspondence between the received speech input and a grammar element included in the plurality of grammar elements.

Abstract
Speech recognition is performed utilizing a dynamically maintained set of grammar elements. A plurality of grammar elements may be identified, and the grammar elements may be ordered based at least in part upon contextual information. In other words, contextual information may be utilized to bias speech recognition. Once a speech input is received, the ordered plurality of grammar elements may be evaluated, and a correspondence between the received speech input and a grammar element included in the plurality of grammar elements may be determined.

13. A system comprising:
-
at least one memory configured to store computer-executable instructions; and at least one processor configured to access the at least one memory and execute the computer-executable instructions to; identify a plurality of grammar elements associated with speech recognition; receive a speech input; identify at least one item of contextual information; and determine, based at least in part upon the contextual information, a correspondence between the received speech input and a grammar element included in the plurality of grammar elements. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)
