SpeechRecognitionEngine.SetInputToDefaultAudioDevice 메서드

정의

네임스페이스:

System.Speech.Recognition

어셈블리:

System.Speech.dll

기본 오디오 디바이스에서 입력을 받도록 SpeechRecognitionEngine 개체를 구성합니다.

public:
 void SetInputToDefaultAudioDevice();

public void SetInputToDefaultAudioDevice ();

member this.SetInputToDefaultAudioDevice : unit -> unit

Public Sub SetInputToDefaultAudioDevice ()

예제

다음 예제에서는 기본 음성 인식 기능을 보여 주는 콘솔 애플리케이션 부분을 보여 줍니다. 이 예제에서는 기본 오디오 디바이스에서 출력을 사용 하 여, 여러 수행 비동기 인식 작업 및 사용자 utters 구의 종료 "종료"입니다.
