GrammarBuilder.Addition Operator (Choices, GrammarBuilder)
Assembly: System.Speech (in System.Speech.dll)
- Type: System.Speech.Recognition.Choices
The first grammar element, which represents a set of alternatives.
- Type: System.Speech.Recognition.GrammarBuilder
The second grammar element.
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.
When you combine Choices and 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 Understanding SemanticResultValue and SemanticResultKey Objects.
