GrammarBuilder Implicit Conversion (SemanticResultValue to GrammarBuilder)

Converts a SemanticResultValue object to a GrammarBuilder object.

Namespace:  Microsoft.Speech.Recognition
Assembly:  Microsoft.Speech (in Microsoft.Speech.dll)

Syntax

'Declaration
Public Shared Widening Operator CType ( _
    semanticValue As SemanticResultValue _
) As GrammarBuilder
'Usage
Dim input As SemanticResultValue
Dim output As GrammarBuilder

output = CType(input, GrammarBuilder)

public static implicit operator GrammarBuilder (
    SemanticResultValue semanticValue
)

Parameters

• semanticValue
  Type: Microsoft.Speech.Recognition.SemanticResultValue
  The SemanticResultValue object to convert.

Return Value

Type: Microsoft.Speech.Recognition.GrammarBuilder
The converted SemanticResultValue object.

Remarks

Implicit conversion creates a new instance of GrammarBuilder. This conversion operator is equivalent to calling GrammarBuilder(SemanticResultValue) and specifying semanticValue for the value.

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 Choicesobject, in the construction of a Choices object from two SemanticResultValue objects, and in the construction of a Grammar object from a SemanticResultKey object.

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";
