GrammarBuilder.Addition Operator (GrammarBuilder, GrammarBuilder)
Creates a new GrammarBuilder that contains a sequence of two GrammarBuilder objects.
Namespace: Microsoft.Speech.Recognition
Assembly: Microsoft.Speech (in Microsoft.Speech.dll)
Syntax
'Declaration
Public Shared Operator + ( _
builder1 As GrammarBuilder, _
builder2 As GrammarBuilder _
) As GrammarBuilder
'Usage
Dim builder1 As GrammarBuilder
Dim builder2 As GrammarBuilder
Dim returnValue As GrammarBuilder
returnValue = (builder1 + builder2)
public static GrammarBuilder operator +(
GrammarBuilder builder1,
GrammarBuilder builder2
)
Parameters
- builder1
Type: Microsoft.Speech.Recognition.GrammarBuilder
The first grammar element.
- builder2
Type: Microsoft.Speech.Recognition.GrammarBuilder
The second grammar element.
Return Value
Type: Microsoft.Speech.Recognition.GrammarBuilder
Returns a GrammarBuilder for the sequence of the builder1 parameter followed by the builder2 parameter.
Remarks
GrammarBuilder supports conversions from the following classes.
This method accepts the objects listed above for the builder1 and builder2 parameters. For more information, see the Implicit operators.
Important
When you combine GrammarBuilder objects that contain SemanticResultValue or SemanticResultKey instances, make sure you avoid creating duplicate semantic elements with the same key name or multiple semantic elements that could repeatedly modify the Value property of a SemanticValue object. The speech recognizer can throw an exception if it encounters these circumstances. For more information about building a speech recognition grammar that contains semantic information, see Add Semantics to a GrammarBuilder Grammar (Microsoft.Speech).
