SpeechRecognizer.LoadGrammarAsync Method (Grammar)
Asynchronously loads a speech recognition grammar.
Assembly: System.Speech (in System.Speech.dll)
When the recognizer completes this asynchronous operation, it raises a LoadGrammarCompleted event. The recognizer throws an exception if the speech recognition grammar is already loaded, is being asynchronously loaded, or has failed to load into any recognizer. If the recognizer is running, applications must use RequestRecognizerUpdate to pause the speech recognition engine before loading, unloading, enabling, or disabling a grammar.
To load a speech recognition grammar synchronously, use the LoadGrammar method.
