Muncul ketika SpeechRecognitionEngine telah mengenali kata atau kata yang mungkin merupakan komponen dari beberapa frasa lengkap dalam tata bahasa.

public:
 event EventHandler<System::Speech::Recognition::SpeechHypothesizedEventArgs ^> ^ SpeechHypothesized;
public event EventHandler<System.Speech.Recognition.SpeechHypothesizedEventArgs> SpeechHypothesized;
member this.SpeechHypothesized : EventHandler<System.Speech.Recognition.SpeechHypothesizedEventArgs> 
Public Custom Event SpeechHypothesized As EventHandler(Of SpeechHypothesizedEventArgs)

Jenis Acara

EventHandler<SpeechHypothesizedEventArgs>

Contoh

Contoh berikut mengenali frasa seperti "Tampilkan daftar artis dalam kategori jazz". Contohnya menggunakan SpeechHypothesized peristiwa untuk menampilkan frasa frasa yang tidak lengkap di konsol saat dikenali.

using System;  
using System.Speech.Recognition;  

namespace SampleRecognition  
{  
  class Program  
  {  
    static void Main(string[] args)  

    // Initialize an in-process speech recognition engine.  
    {  
      using (SpeechRecognitionEngine recognizer =  
         new SpeechRecognitionEngine())  
      {  

        // Create a grammar.  
        //  Create lists of alternative choices.  
        Choices listTypes = new Choices(new string[] { "albums", "artists" });  
        Choices genres = new Choices(new string[] {   
          "blues", "classical", "gospel", "jazz", "rock" });  

        //  Create a GrammarBuilder object and assemble the grammar components.  
        GrammarBuilder mediaMenu = new GrammarBuilder("Display the list of");  
        mediaMenu.Append(listTypes);  
        mediaMenu.Append("in the");  
        mediaMenu.Append(genres);  
        mediaMenu.Append("category.");  

        //  Build a Grammar object from the GrammarBuilder.  
        Grammar mediaMenuGrammar = new Grammar(mediaMenu);  
        mediaMenuGrammar.Name = "Media Chooser";  

        // Attach event handlers.  
        recognizer.LoadGrammarCompleted +=  
          new EventHandler<LoadGrammarCompletedEventArgs>(recognizer_LoadGrammarCompleted);  
        recognizer.SpeechRecognized +=  
          new EventHandler<SpeechRecognizedEventArgs>(recognizer_SpeechRecognized);  
        recognizer.SpeechHypothesized +=  
          new EventHandler<SpeechHypothesizedEventArgs>(recognizer_SpeechHypothesized);  

        // Load the grammar object to the recognizer.  
        recognizer.LoadGrammarAsync(mediaMenuGrammar);  

        // Set the input to the recognizer.  
        recognizer.SetInputToDefaultAudioDevice();  

        // Start asynchronous recognition.  
        recognizer.RecognizeAsync();  

        // Keep the console window open.  
        Console.ReadLine();  
      }  
    }  

    // Handle the SpeechHypothesized event.  
    static void recognizer_SpeechHypothesized(object sender, SpeechHypothesizedEventArgs e)  
    {  
      Console.WriteLine("Speech hypothesized: " + e.Result.Text);  
    }  

    // Handle the LoadGrammarCompleted event.  
    static void recognizer_LoadGrammarCompleted(object sender, LoadGrammarCompletedEventArgs e)  
    {  
      Console.WriteLine("Grammar loaded: " + e.Grammar.Name);  
      Console.WriteLine();  
    }  

    // Handle the SpeechRecognized event.  
    static void recognizer_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)  
    {  
      Console.WriteLine();   
      Console.WriteLine("Speech recognized: " + e.Result.Text);  
    }  
  }  
}

Keterangan

SpeechRecognitionEngine menghasilkan banyak SpeechHypothesized peristiwa saat mencoba mengidentifikasi frasa input. Anda dapat mengakses teks frasa yang dikenali sebagian di Result properti SpeechHypothesizedEventArgs objek di handler untuk peristiwa tersebut SpeechHypothesized . Biasanya, menangani peristiwa ini hanya berguna untuk penelusuran kesalahan.

SpeechHypothesizedEventArgs berasal dari RecognitionEventArgs.

Untuk informasi selengkapnya, lihat EndSilenceTimeoutAmbiguous properti dan Recognizemetode , , EmulateRecognizeRecognizeAsync, dan EmulateRecognizeAsync .

Saat membuat SpeechHypothesized delegasi, Anda mengidentifikasi metode yang akan menangani peristiwa. Untuk mengaitkan peristiwa dengan penanganan aktivitas Anda, tambahkan instans delegasi ke peristiwa. Penanganan aktivitas dipanggil setiap kali peristiwa terjadi, kecuali Jika Anda menghapus delegasi. Untuk informasi selengkapnya tentang delegasi penanganan aktivitas, lihat Peristiwa dan Delegasi.
