| GrammarBuilder Class Example See Also Send Feedback |
Converts a SemanticResultKey object to a GrammarBuilder object.
Namespace:
Microsoft.Speech.Recognition
Assembly:
Microsoft.Speech (in Microsoft.Speech.dll)
Syntax
| Visual Basic (Declaration) |
|---|
Public Shared Widening Operator CType ( _ semanticKey As SemanticResultKey _ ) As GrammarBuilder |
| Visual Basic (Usage) |
|---|
Dim input As SemanticResultKey Dim output As GrammarBuilder output = CType(input, GrammarBuilder) |
| C# |
|---|
public static implicit operator GrammarBuilder ( SemanticResultKey semanticKey ) |
Parameters
- semanticKey
- Type: Microsoft.Speech.Recognition..::..SemanticResultKey
The semantic key to convert.
Return Value
Type: Microsoft.Speech.Recognition..::..GrammarBuilderThe converted SemanticResultKey object.
Remarks
Implicit conversion creates a new instance of GrammarBuilder. This conversion operator is equivalent to calling GrammarBuilder(SemanticResultKey) and specifying semanticKey for the key.
Examples
The following example creates a speech recognition grammar that can recognize a response to a "yes" or "no" question. The implicit conversion operator is used in the construction of a SemanticResultValue object from a Choices object, in the construction of a Choices object from two SemanticResultValue objects, and in the construction of a Grammar object from a SemanticResultKey object.
| C# | Copy Code |
|---|---|
Choices yesChoices = new Choices(new string[] {"yes", "yup", "yah"});
SemanticResultValue yesValue =
new SemanticResultValue(yesChoices, true);
Choices noChoices = new Choices(new string[] { "no", "nope", "nah" });
SemanticResultValue noValue =
new SemanticResultValue(noChoices, false);
SemanticResultKey yesnoKey =
new SemanticResultKey("yesno", new Choices(new GrammarBuilder[] { yesValue, noValue }));
Grammar yesnoGrammar = new Grammar(yesnoKey);
yesnoGrammar.Name = "yesno";
