SpeechRecognitionRejectedEventArgs 類別

定義

命名空間:

System.Speech.Recognition

組件:

System.Speech.dll

套件:

System.Speech v9.0.0

來源:

RecognitionEventArgs.cs

提供 SpeechRecognitionRejected 與 SpeechRecognitionRejected 事件的資訊。

public ref class SpeechRecognitionRejectedEventArgs : System::Speech::Recognition::RecognitionEventArgs

public class SpeechRecognitionRejectedEventArgs : System.Speech.Recognition.RecognitionEventArgs

type SpeechRecognitionRejectedEventArgs = class
    inherit RecognitionEventArgs

Public Class SpeechRecognitionRejectedEventArgs
Inherits RecognitionEventArgs

SpeechRecognitionRejectedEventArgs

範例

下列範例會辨識「在音樂類別中顯示藝人清單」或「顯示相簿」等片語。 此範例會使用 事件的處理常式 SpeechRecognitionRejected ，在語音輸入無法與文法內容相符時，在主控台中顯示通知，且有足夠的信心來產生成功的辨識。

備註

事件 SpeechRecognitionRejected 是由 SpeechRecognizer 和 SpeechRecognitionEngine 類別引發。

當辨識作業中沒有任何替代專案具有足以接受的信賴分數時，語音辨識引擎會產生SpeechRecognitionRejected事件。 可透過 Result 屬性取得拒絕片語的詳細資訊。

SpeechRecognitionRejectedEventArgs 衍生自 RecognitionEventArgs 。

屬性

Result

取得與語音辨識事件關聯的辨識結果資料。 (繼承來源 RecognitionEventArgs)

方法

Equals(Object)	判斷指定的物件是否等於目前的物件。 (繼承來源 Object)
GetHashCode()	做為預設雜湊函式。 (繼承來源 Object)
GetType()	取得目前執行個體的 Type。 (繼承來源 Object)
MemberwiseClone()	建立目前 Object 的淺層複製。 (繼承來源 Object)
ToString()	傳回代表目前物件的字串。 (繼承來源 Object)
