Examples

The following example creates a prompt that includes two bookmarks and sends the output to a WAV file for playback. The handler for the BookmarkReached event writes the name of the bookmark and its position in the audio stream when the event was raised to the console.

using System;  
using System.Speech.Synthesis;  

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

      // Initialize a new instance of the SpeechSynthesizer.  
      using (SpeechSynthesizer synth = new SpeechSynthesizer())  
      {  

        // Configure the audio output.   
        synth.SetOutputToWaveFile(@"C:\test\weather.wav");  

        // Create a SoundPlayer instance to play the output audio file.  
        System.Media.SoundPlayer m_SoundPlayer =  
          new System.Media.SoundPlayer(@"C:\test\weather.wav");  

        // Build a prompt and append bookmarks.  
        PromptBuilder builder = new PromptBuilder(  
          new System.Globalization.CultureInfo("en-US"));  
        builder.AppendText(  
          "The weather forecast for today is partly cloudy with some sun breaks.");  
        builder.AppendBookmark("Daytime forecast");  
        builder.AppendText(  
          "Tonight's weather will be cloudy with a 30% chance of showers.");  
        builder.AppendBookmark("Nighttime forecast");  

        // Add a handler for the BookmarkReached event.  
        synth.BookmarkReached +=  
          new EventHandler<BookmarkReachedEventArgs>(synth_BookmarkReached);  

        // Speak the prompt and play back the output file.  
        synth.Speak(builder);  
        m_SoundPlayer.Play();  
      }  

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

    // Write the name and position of the bookmark to the console.  
    static void synth_BookmarkReached(object sender, BookmarkReachedEventArgs e)  
    {  
      Console.WriteLine("Bookmark ({0}) reached at: {1} ",  
        e.Bookmark, e.AudioPosition);  
    }  
  }  
}  

Remarks

A speech synthesis engine will generate a BookmarkReached event if it encounters a bookmark while speaking a prompt using any of the Speak, SpeakAsync, SpeakSsml, or SpeakSsmlAsync methods.
