Speech recognition systems provide computers with the ability to recognize what a user says. These systems use grammars to identify the words and phrases that can be spoken by the user. The Voice tools assist voice application developers with the development of a "command-and-control" grammar, or rule grammar.
Grammars formally define the set of allowable phrases that can be recognized by the speech engine. Command and control grammars specify the valid utterances that a user could say to perform an action or supply information.
These tools simplify the development of command-and-control grammars. The tools support Speech Recognition Grammar Specification (SRGS) and provides an environment in which you can write and syntax check source code.
