Public Shared Operator + ( _
    choices As Choices, _
    builder As GrammarBuilder _
) As GrammarBuilder

    GrammarBuilder builder

Parameters

Return Value

Type: Microsoft.Speech.Recognition.GrammarBuilder
Returns a GrammarBuilder for the sequence of the choices parameter followed by the builder parameter.

Remarks

GrammarBuilder supports conversions from the following classes.

This method accepts the objects listed above for the builder parameter. For more information, see the Implicit operators.

Important

When you combine Choices or 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).
