SpeechRecognitionEngine.SpeechHypothesized SpeechRecognitionEngine.SpeechHypothesized SpeechRecognitionEngine.SpeechHypothesized SpeechRecognitionEngine.SpeechHypothesized Event

定義

SpeechRecognitionEngine が文法の複数の完全な語句のコンポーネントである可能性がある単語を認識した場合に発生します。Raised when the SpeechRecognitionEngine has recognized a word or words that may be a component of multiple complete phrases in a grammar.

public:
 event EventHandler<System::Speech::Recognition::SpeechHypothesizedEventArgs ^> ^ SpeechHypothesized;
public event EventHandler<System.Speech.Recognition.SpeechHypothesizedEventArgs> SpeechHypothesized;
member this.SpeechHypothesized : EventHandler<System.Speech.Recognition.SpeechHypothesizedEventArgs> 
Public Custom Event SpeechHypothesized As EventHandler(Of SpeechHypothesizedEventArgs) 

次の例では、「アーティスト ジャズのカテゴリの一覧を表示する」などの語句を認識します。The following example recognizes phrases such as "Display the list of artists in the jazz category". この例では、SpeechHypothesizedコンソールで、認識が不完全な語句のフラグメントを表示するイベントです。The example uses the SpeechHypothesized event to display incomplete phrase fragments in the console as they are recognized.

        Choices genres = new Choices(new string[] {   
          "blues", "classical", "gospel", "jazz", "rock" });

注釈

SpeechRecognitionEngine多数生成SpeechHypothesizedのイベントを入力のフレーズを識別しようとしました。The SpeechRecognitionEngine generates numerous SpeechHypothesized events as it attempts to identify an input phrase. 部分的に認識されているフレーズのテキストにアクセスすることができます、Resultのプロパティ、SpeechHypothesizedEventArgsオブジェクト用のハンドラーで、SpeechHypothesizedイベント。You can access the text of partially recognized phrases in the Result property of the SpeechHypothesizedEventArgs object in the handler for the SpeechHypothesized event. 通常、これらのイベントの処理は、のみのデバッグに役立ちます。Typically, handling these events is useful only for debugging.

SpeechHypothesizedEventArgs は、RecognitionEventArgs から派生します。SpeechHypothesizedEventArgs derives from RecognitionEventArgs.

詳細については、次を参照してください。、EndSilenceTimeoutAmbiguousプロパティおよびRecognizeRecognizeAsyncEmulateRecognize、およびEmulateRecognizeAsyncメソッド。For more information see the EndSilenceTimeoutAmbiguous property and the Recognize, RecognizeAsync, EmulateRecognize, and EmulateRecognizeAsync methods.

SpeechHypothesized デリゲートを作成する場合は、イベントを処理するメソッドを指定します。When you create a SpeechHypothesized delegate, you identify the method that will handle the event. イベントをイベント ハンドラーに関連付けるには、デリゲートのインスタンスをイベントに追加します。To associate the event with your event handler, add an instance of the delegate to the event. デリゲートを削除しない限り、そのイベントが発生すると常にイベント ハンドラーが呼び出されます。The event handler is called whenever the event occurs, unless you remove the delegate. イベント ハンドラー デリゲートの詳細については、次を参照してください。イベントとデリゲートします。For more information about event-handler delegates, see Events and Delegates.
