Examples

The following example renders the date 1/29/2009 as a date, in month, day, year order.

using System;
using System.Speech.Synthesis;

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

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

      // Configure the audio output.
      synth.SetOutputToDefaultAudioDevice();

      // Build an SSML prompt in a string.
      string str = "<speak version=\"1.0\"";
      str += " xmlns=\"http://www.w3.org/2001/10/synthesis\"";
      str += " xml:lang=\"en-US\">";
      str += "<say-as type=\"date:mdy\"> 1/29/2009 </say-as>";
      str += "</speak>";

      // Speak the contents of the prompt synchronously.
      synth.SpeakSsml(str);

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

Remarks

The contents of the textToSpeak parameter must include a speak element and must conform to the Speech Synthesis Markup Language (SSML) Version 1.0. For more information, see Speech Synthesis Markup Language Reference.

To asynchronously speak a string that contains SSML markup, use the SpeakSsmlAsync method. You can use Speak to initiate the synchronous speaking of a string that does not contain SSML markup.

During a call to this method, the SpeechSynthesizer can raise the following events:

StateChanged. Raised when the speaking state of the synthesizer changes.
SpeakStarted. Raised when the synthesizer begins generating speech.
PhonemeReached. Raised each time the synthesizer reaches a letter or combination of letters that constitute a discreet sound of speech in a language.
SpeakProgress. Raised each time the synthesizer completes speaking a word.
VisemeReached. Raised each time spoken output requires a change in the position of the mouth or the facial muscles used to produce speech.
BookmarkReached. Raised when the synthesizer encounters a bookmark in a prompt.
VoiceChange. Raised when the speaking voice for the synthesizer changes.

The SpeechSynthesizer does not raise the SpeakCompleted event while processing the SpeakSsml method.
