Tanıma işlemi başarılı olursa tanıma sonucu; aksi takdirde , null.

Örnekler

Aşağıdaki örnek, işlem içi tanıyıcı ile yöntemini kullanarak SpeechRecognitionEngine.RecognizeAsync bir konuşma tanıma dil bilgisi üzerinde zaman uyumsuz konuşma tanıma gerçekleştirir. Örnek, konuşma tanıma dil bilgisini bir Grammar nesneye derlemeden önce oluşturmak için ve GrammarBuilder nesnelerini kullanırChoices. Olay işleyicisi SpeechRecognitionEngine.RecognizeCompleted , tanıma işlemiyle ilgili bilgileri konsola gönderir.
