With the members of the Speech Recognition Grammar Specification Version 1.0 (SRGS).namespace, you can programmatically create grammars that comply with the W3C
Defines a design-time object that is used to build strongly-typed runtime grammars that conform to the Speech Recognition Grammar Specification (SRGS) Version 1.0.
Defines the base class for classes in thenamespace that correspond to the elements in an SRGS grammar.
Compiles SrgsDocument and XML-format grammar files into binary grammar files with the .cfg extension and sends the output to a stream.
Represents a grammar element that contains phrases or other entities that a user can speak to produce a successful recognition.
Represents an element for associating a semantic value with a phrase in a grammar.
Represents a list of alternative words or phrases, any one of which may be used to match speech input.
Represents a grammar rule.
Represents the grammar element that specifies a reference to a rule.
Represents a collection of SrgsRule objects.
Represents a tag that contains ECMAScript that is run when the rule is matched.
Defines methods and properties that can be used to match a given string with a spoken phrase.
Represents the textual content of grammar elements defined by the World Wide Web Consortium (W3C) Speech Recognition Grammar Specification (SRGS) Version 1.0.
Represents a word or short phrase that can be recognized.
To create an SRGS grammar programmatically, you construct an empty SrgsDocument instance and add instances of classes that represent SRGS elements. The SrgsItem, SrgsOneOf, SrgsRule, SrgsRuleRef, SrgsSemanticInterpretationTag, and SrgsToken classes represent elements defined in the SRGS specification. Some of the properties of the SrgsDocument class represent attributes in the SRGS specification, such as Root, Mode, Culture, and XmlBase. See SRGS Grammar XML for a reference to the elements and attributes of the SRGS specification as supported by System.Speech.
With the SrgsSubset class, you can optimize recognition of phrases in a grammar by specifying subsets of a complete phrase that will be allowed to constitute a match, and by selecting a matching mode from the SubsetMatchingMode enumeration.
See Create Grammars Using SrgsGrammar in the System Speech Programming Guide for .NET Framework 4.0 for more information and examples.
