Important
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 Add Semantics to a GrammarBuilder Grammar.
