Grammar.SpeechRecognized 事件

定义

命名空间:

System.Speech.Recognition

程序集:

System.Speech.dll

包:

System.Speech v9.0.0-preview.3.24172.9

Source:

Grammar.cs

当语音识别器执行使用 Grammar 对象的标识时引发。

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 Event SpeechRecognized As EventHandler(Of SpeechRecognizedEventArgs) 

事件类型

EventHandler<SpeechRecognizedEventArgs>

示例

以下示例演示如何对 Grammar 对象的 SpeechRecognized 事件使用事件处理程序。 它将识别结果输出到 控制台。

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);  
  }  
}  

注解

语音识别器在识别输入时也会引发 SpeechRecognized 事件。 对象的 GrammarSpeechRecognized 事件在语音识别器 SpeechRecognized 的事件 之前引发。 有关详细信息， SpeechRecognizer.SpeechRecognized请参阅 、 SpeechRecognitionEngine.SpeechRecognized和 RecognizeCompleted 事件。

特定于特定语法的任何任务应始终由对象的 SpeechRecognized 事件的处理程序Grammar处理。
