Examples

The following example creates a speech recognition grammar in an SrgsDocument that contains a relative rule reference to the cities.xml file, and specifies a URI to use to resolve the rule reference. The content of the cities.xml file appears in the XML example that follows the C# example.

private static Grammar CreateSrgsDocumentGrammar3()  
{  
  // Create the SrgsDocument.  
  SrgsDocument document = new SrgsDocument();  

  // Create the Main rule and add it to the document.  
  SrgsRule mainRule = new SrgsRule("Main");  
  mainRule.Scope = SrgsRuleScope.Public;  

  SrgsItem item = new SrgsItem("Can I get a shuttle in");  

  // Create a relative URI for the cities rule.  
  Uri ruleUri = new Uri("cities.xml#Cities", UriKind.Relative);  

  item.Add(new SrgsRuleRef(ruleUri));  

  mainRule.Add(item);  
  document.Rules.Add(mainRule);  

  // Set the root rule.  
  document.Root = mainRule;  

  // Create the grammar.  
  Uri baseUri = new Uri(@"file://c:\temp\");  
  Grammar citiesGrammar = new Grammar(document, null, baseUri);  
  citiesGrammar.Name = "SrgsDocument Cities Grammar 3";  

  return citiesGrammar;  
}

Remarks

This constructor does not pass any parameters to the initialization handler, and the SrgsDocument should not contain an initialization handler that requires arguments.

This constructor does not validate baseUri. However, the LoadGrammar method of a SpeechRecognitionEngine or SpeechRecognizer object throws an exception if it cannot resolve all of the rule references in the grammar description. If baseUri is not null, the LoadGrammar method uses the URI to resolve any rule references that it cannot otherwise resolve. If baseUri represents a file, then the LoadGrammar method uses both the designated file and the file's directory when it attempts to resolve relative rule references.

Remarks

This constructor does not pass any parameters to the initialization handler, and the description should not define an initialization handler that requires arguments.

This constructor can create a Grammar instance from the following formats:

• XML-format files that conform to the W3C Speech Recognition Grammar Specification (SRGS) Version 1.0

• Grammars that have been compiled to a binary file with a .cfg file extension

This constructor compiles XML-format grammar files to a binary format to optimize them for loading and consumption by a speech recognition engine. You can reduce the amount of time required to construct a Grammar object from an XML-format grammar by compiling the grammar in advance, using one of the Compile methods.

This constructor does not validate baseUri. However, the LoadGrammar method of a SpeechRecognitionEngine or SpeechRecognizer object throws an exception if it cannot resolve all of the rule references in the grammar description. If baseUri is not null, the LoadGrammar method uses the URI to resolve any rule references that it cannot otherwise resolve. If baseUri represents a file, then the LoadGrammar uses both the designated file and the file's directory when it attempts to resolve relative rule references.

The following example creates a speech recognition grammar in an SrgsDocument instance and specifies a rule to use as the root rule of the grammar. The example constructs a Grammar object from the SrgsDocument instance and loads it into the speech recognition engine.

        document.Rules.Add(mainRule);  

        // Create the Grammar object and specify which rule to use as the root.  
        Grammar citiesGrammar = new Grammar(document,"Main");  

        // Load the grammar object to the recognizer.

        Console.WriteLine("Starting asynchronous recognition...");  

        // Keep the console window open.  
        Console.ReadLine();  
      }  
    }  

    // Handle the SpeechRecognized event.  
    static void recognizer_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)  
    {  
      Console.WriteLine("  Speech recognized: " + e.Result.Text);  
    }  
  }  
}

Remarks

This constructor does not pass any parameters to the initialization handler, and the description should not define an initialization handler that requires arguments.

This constructor can create a Grammar instance from the following formats:

• XML-format files that conform to the W3C Speech Recognition Grammar Specification (SRGS) Version 1.0

• Grammars that have been compiled to a binary file with a .cfg file extension

This constructor compiles XML-format grammar files to a binary format to optimize them for loading and consumption by a speech recognition engine. You can reduce the amount of time required to construct a Grammar object from an XML-format grammar by compiling the grammar in advance, using one of the Compile methods.

To create a Grammar that specifies a base URI to use to resolve relative rule references, open a file stream for the file and use the Grammar constructor.

Remarks

This constructor does not pass any parameters to the initialization handler, and the description should not define an initialization handler that requires arguments.

This constructor can create a Grammar instance from the following formats:

• XML-format files that conform to the W3C Speech Recognition Grammar Specification (SRGS) Version 1.0

• Grammars that have been compiled to a binary file with a .cfg file extension

This constructor compiles XML-format grammar files to a binary format to optimize them for loading and consumption by a speech recognition engine. You can reduce the amount of time required to construct a Grammar object from an XML-format grammar by compiling the grammar in advance, using one of the Compile methods.

An SRGS grammar can define a root rule. To create a Grammar object from a stream and specify a root rule, use the Grammar or Grammar constructor.

To create a Grammar object from a stream and specify a base URI to use to resolve relative rule references, use the Grammar constructor.
