public void LoadGrammar (System.Speech.Recognition.Grammar grammar);
member this.LoadGrammar : System.Speech.Recognition.Grammar -> unit

Parametri

grammar
Grammar Grammar Grammar

La grammatica di riconoscimento vocale da caricare.The speech recognition grammar to load.

Esempi

L'esempio seguente fa parte di un'applicazione console che carica una grammatica di riconoscimento vocale e illustra l'input emulato asincrono, i risultati del riconoscimento associati e gli eventi associati generati dal riconoscimento vocale.The following example is part of a console application that loads a speech recognition grammar and demonstrates asynchronous emulated input, the associated recognition results, and the associated events raised by the speech recognizer. Se il riconoscimento vocale di Windows non è in esecuzione, l'avvio dell'applicazione avvierà anche il riconoscimento vocale di Windows.If Windows Speech Recognition is not running, then starting this application will also start Windows Speech Recognition. Se il riconoscimento vocale di Windows è **** in stato di sospensione EmulateRecognizeAsync , restituisce sempre null.If Windows Speech Recognition is in the Sleeping state, then EmulateRecognizeAsync always returns null.

Commenti

Il riconoscimento condiviso genera un'eccezione se la grammatica del riconoscimento vocale è già caricata, viene caricata in modo asincrono o non è stata caricata in alcun riconoscimento.The shared recognizer throws an exception if the speech recognition grammar is already loaded, is being asynchronously loaded, or has failed to load into any recognizer. Se il riconoscimento è in esecuzione, le applicazioni devono RequestRecognizerUpdate usare per sospendere il motore di riconoscimento vocale prima di caricare, scaricare, abilitare o disabilitare una grammatica.If the recognizer is running, applications must use RequestRecognizerUpdate to pause the speech recognition engine before loading, unloading, enabling, or disabling a grammar.

Per caricare una grammatica di riconoscimento vocale in modo asincrono, LoadGrammarAsync usare il metodo.To load a speech recognition grammar asynchronously, use the LoadGrammarAsync method.
