Examples

The following example builds a prompt containing two sentences separated by a break and speaks the prompt to the default audio device on the computer.

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.SetOutputToDefaultAudioDevice();  

        // Build a prompt with two sentences separated by a break.  
        PromptBuilder builder = new PromptBuilder(  
          new System.Globalization.CultureInfo("en-US"));  
        builder.AppendText(  
          "Tonight's movie showings in theater A are at 5:45, 7:15, and 8:45.");  
        builder.AppendBreak(PromptBreak.Medium);  
        builder.AppendText(  
          "Tonight's movie showings in theater B are at 5:15, 7:30, and 9:15.");  

        // Speak the prompt.  
        synth.Speak(builder);  
      }  

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

Remarks

The values in the PromptBreak enumeration represent a range of separation intervals (pauses) between word boundaries. The speech synthesis engine determines the exact duration of the interval. When a break is requested, one of these values is passed to the text-to-speech (TTS) engine, which contains a mapping between these values and the corresponding millisecond break values.

The value None represents the absence of a pause between word boundaries and can be used to remove a break where one would normally occur. The remaining values are listed in order of increasing durations for breaks.
