@@@배블 시간 제한이 RecognizeCompleted 이벤트를 생성했는지 여부를 나타내는 값을 가져옵니다.

Public ReadOnly Property BabbleTimeout As Boolean

속성 값

Boolean

true 가 속성에 SpeechRecognitionEngine 지정된 BabbleTimeout 것보다 오랫동안 백그라운드 노이즈만 검색한 경우 이고, 그렇지 않으면 false입니다.

예제

스피치 인식 그래 머의 비동기 음성 인식을 수행 하는 다음 예제에서는 사용 하는 SpeechRecognitionEngine.RecognizeAsync in process 인식기를 사용 하 여 메서드. 예제에서는 Choices 하 고 GrammarBuilder 스피치 인식 그래 머를 빌드하기 전에 만들려는 개체를 Grammar 개체입니다. 에 대 한 처리기를 SpeechRecognitionEngine.RecognizeCompleted 이벤트 콘솔로 인식 작업에 대 한 정보를 출력 합니다.
