Grammar.SpeechRecognized 事件

定義

命名空間:

System.Speech.Recognition

組件:

System.Speech.dll

套件:

System.Speech v9.0.0-rc.2.24473.5

來源:

Grammar.cs

當語音辨識器使用 Grammar 物件執行辨識時引發。

public:
 event EventHandler<System::Speech::Recognition::SpeechRecognizedEventArgs ^> ^ SpeechRecognized;

public event EventHandler<System.Speech.Recognition.SpeechRecognizedEventArgs> SpeechRecognized;

member this.SpeechRecognized : EventHandler<System.Speech.Recognition.SpeechRecognizedEventArgs> 

Public Custom Event SpeechRecognized As EventHandler(Of SpeechRecognizedEventArgs) 

事件類型

EventHandler<SpeechRecognizedEventArgs>

範例

下列範例顯示物件事件的事件處理常式 GrammarSpeechRecognized 用法。 它會將辨識結果輸出至 主控台。

public partial class Form1 : Form  
{  
  SpeechRecognitionEngine sre;  

  public Form1()  
  {  
  InitializeComponent();  

  // Create an in-process speech recognizer.  
  sre = new SpeechRecognitionEngine();  

  // Configure input to the speech recognizer.  
  sre.SetInputToDefaultAudioDevice();  

  // Create a simple grammar and load it.  
  Grammar testGrammar = new Grammar(new GrammarBuilder("testing"));  
  sre.LoadGrammarAsync(testGrammar);  

  // Add a handler for the grammar's speech recognized event.  
  testGrammar.SpeechRecognized += new EventHandler<SpeechRecognizedEventArgs>(testGrammar_SpeechRecognized);  

  // Start asynchronous speech recognition.  
  sre.RecognizeAsync();  
  }  

  // Handle the grammar's SpeechRecognized event, output the recognized text.  
  void testGrammar_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)  
  {  
    Console.WriteLine("Recognized text: " + e.Result.Text);  
  }  
}  

備註

語音辨識器也會在辨識輸入時引發 SpeechRecognized 事件。 物件 GrammarSpeechRecognized 的事件會在語音辨識器 SpeechRecognized 的事件之前引發。 如需詳細資訊，請參閱 SpeechRecognizer.SpeechRecognized 、 SpeechRecognitionEngine.SpeechRecognized 和 RecognizeCompleted 事件。

特定文法的特定任何工作應該一律由物件的 SpeechRecognized 事件處理常式 Grammar 處理。
