SrgsRule Class

Represents a grammar rule.

Namespace: Microsoft.Speech.Recognition.SrgsGrammar
Assembly: Microsoft.Speech (in microsoft.speech.dll)

public sealed class SrgsRule

public final class SrgsRule
public final class SrgsRule

Use the SrgsRule class to create a new rule at run time or to modify a rule in an existing grammar stream or file at run time.

The phrases defined by grammar rules form the basis of the recognizer's language model in the Microsoft.Speech.Recognition.SrgsGrammar namespace. This basis limits the set of possible phrases that the recognizer must be able to recognize.

A rule consists of child elements that specify the sequence in which the phrases must be spoken. These elements are represented by objects such as SrgsItem, SrgsOneOf, and SrgsRuleRef elements. Use the Elements property to access the collection of child elements a rule contains.

You can specify whether a rule can be activated for recognition and when it can be referenced by other rules by using the Scope property.

This class represents the rule element that is defined in the World Wide Web Consortium (W3C) Speech Recognition Grammar Specification (SRGS).
