SpeechRecognizer.Grammars 属性

  • 参考

定义

命名空间:
System.Speech.Recognition
程序集:
System.Speech.dll

获取在此 Grammar 实例中加载的 SpeechRecognizer 对象的集合。

public:
 property System::Collections::ObjectModel::ReadOnlyCollection<System::Speech::Recognition::Grammar ^> ^ Grammars { System::Collections::ObjectModel::ReadOnlyCollection<System::Speech::Recognition::Grammar ^> ^ get(); };
public System.Collections.ObjectModel.ReadOnlyCollection<System.Speech.Recognition.Grammar> Grammars { get; }
member this.Grammars : System.Collections.ObjectModel.ReadOnlyCollection<System.Speech.Recognition.Grammar>
Public ReadOnly Property Grammars As ReadOnlyCollection(Of Grammar)

属性值

ReadOnlyCollection<Grammar>

应用程序加载到共享识别器的当前实例的 Grammar 对象的集合。

示例

下面的示例将信息输出到控制台，以便将每个语音识别语法加载到共享语音识别器。

using System;  
using System.Collections.Generic;  
using System.Speech.Recognition;  
using System.Threading;  

namespace SharedRecognizer  
{  
  class Program  
  {  
    static void Main(string[] args)  
    {  
      using (SpeechRecognizer recognizer = new SpeechRecognizer())  
      {  
        Grammar sampleGrammar = new Grammar(new GrammarBuilder("sample phrase"));  
        sampleGrammar.Name = "Sample Grammar";  
        recognizer.LoadGrammar(sampleGrammar);  

        OutputGrammarList(recognizer);  
      }  

      Console.WriteLine();  
      Console.WriteLine("Press any key to exit...");  
      Console.ReadKey();  
    }  

    private static void OutputGrammarList(SpeechRecognizer recognizer)  
    {  
      List<Grammar> grammars = new List<Grammar>(recognizer.Grammars);  
      if (grammars.Count > 0)  
      {  
        Console.WriteLine("Loaded grammars:");  
        foreach (Grammar g in grammars)  
        {  
          Console.WriteLine("  Grammar: {0}",  
            (g.Name != null) ? g.Name : "<no name>");  
        }  
      }  
      else  
      {  
        Console.WriteLine("No grammars loaded.");  
      }  
    }  
}

注解

此属性不返回由其他应用程序加载的任何语音识别语法。
