SpeechRecognitionEngine.SetInputToWaveFile(String) SpeechRecognitionEngine.SetInputToWaveFile(String) SpeechRecognitionEngine.SetInputToWaveFile(String) SpeechRecognitionEngine.SetInputToWaveFile(String) Method

定義

SpeechRecognitionEngine オブジェクトを、WAVE オーディオ形式 (.wav) ファイルからの入力を受け取るように構成します。Configures the SpeechRecognitionEngine object to receive input from a Waveform audio format (.wav) file.

public:
 void SetInputToWaveFile(System::String ^ path);
public void SetInputToWaveFile (string path);
member this.SetInputToWaveFile : string -> unit
Public Sub SetInputToWaveFile (path As String)

パラメーター

path
String String String String

入力として使用するファイルのパス。The path of the file to use as input.

次の例では、.wav ファイルのオーディオの認識を実行し、コンソールに、認識されたテキストを書き込みます。The following example performs recognition on the audio in a .wav file and writes the recognized text to the console.

using System;  
using System.IO;  
using System.Speech.Recognition;  
using System.Speech.AudioFormat;  

namespace SampleRecognition  
{  
  class Program  
  {  
    static bool completed;  

    static void Main(string[] args)  

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

        // Create and load a grammar.  
        Grammar dictation = new DictationGrammar();  
        dictation.Name = "Dictation Grammar";  

        recognizer.LoadGrammar(dictation);  

        // Configure the input to the recognizer.  
recognizer.SetInputToWaveFile(@"c:\temp\SampleWAVInput.wav");  

        // Attach event handlers for the results of recognition.  
        recognizer.SpeechRecognized +=   
          new EventHandler<SpeechRecognizedEventArgs>(recognizer_SpeechRecognized);  
        recognizer.RecognizeCompleted +=   
          new EventHandler<RecognizeCompletedEventArgs>(recognizer_RecognizeCompleted);  

        // Perform recognition on the entire file.  
        Console.WriteLine("Starting asynchronous recognition...");  
        completed = false;  
        recognizer.RecognizeAsync();  

        // Keep the console window open.  
        while (!completed)  
        {  
          Console.ReadLine();  
        }  
        Console.WriteLine("Done.");  
      }  

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

    // Handle the SpeechRecognized event.  
    static void recognizer_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)  
    {  
      if (e.Result != null && e.Result.Text != null)  
      {  
        Console.WriteLine("  Recognized text =  {0}", e.Result.Text);  
      }  
      else  
      {  
        Console.WriteLine("  Recognized text not available.");  
      }  
    }  

    // Handle the RecognizeCompleted event.  
    static void recognizer_RecognizeCompleted(object sender, RecognizeCompletedEventArgs e)  
    {  
      if (e.Error != null)  
      {  
        Console.WriteLine("  Error encountered, {0}: {1}",  
        e.Error.GetType().Name, e.Error.Message);  
      }  
      if (e.Cancelled)  
      {  
        Console.WriteLine("  Operation cancelled.");  
      }  
      if (e.InputStreamEnded)  
      {  
        Console.WriteLine("  End of stream encountered.");  
      }  
      completed = true;  
    }  
  }  
}  

注釈

認識エンジンでは、認識操作中に、入力ファイルの末尾に達すると、使用可能な入力の認識操作を終了します。If the recognizer reaches the end of the input file during a recognition operation, the recognition operation finalizes with the available input. 後続の認識操作は、認識エンジンに対する入力を更新する場合を除き、例外を生成できます。Any subsequent recognition operations can generate an exception, unless you update the input to the recognizer.
