Important note Important

Caution is recommended when combining Choices or GrammarBuilder objects that contain SemanticResultValue or SemanticResultKey instances with other grammar elements. The speech recognizer can throw an exception when using a speech recognition grammar that contains duplicate semantic elements with the same key name or multiple semantic elements that could repeatedly modify the value of the same semantic element. For more information about building a speech recognition grammar that contains semantic information, see Using SemanticResultKey and SemanticResultValue Objects.
