Examples

The following example is part of a console application that initializes a SpeechSynthesizer object and outputs to the console a list of the installed voices (engines for speech synthesis) and demonstrates the information that is available for each voice.

using System;  
using System.Speech.Synthesis;  
using System.Speech.AudioFormat;  

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

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

        // Output information about all of the installed voices.   
        Console.WriteLine("Installed voices -");  
        foreach (InstalledVoice voice in synth.GetInstalledVoices())  
        {  
          VoiceInfo info = voice.VoiceInfo;  
          string AudioFormats = "";  
          foreach (SpeechAudioFormatInfo fmt in info.SupportedAudioFormats)  
          {  
            AudioFormats += String.Format("{0}\n",  
            fmt.EncodingFormat.ToString());  
          }  

          Console.WriteLine(" Name:          " + info.Name);  
          Console.WriteLine(" Culture:       " + info.Culture);  
          Console.WriteLine(" Age:           " + info.Age);  
          Console.WriteLine(" Gender:        " + info.Gender);  
          Console.WriteLine(" Description:   " + info.Description);  
          Console.WriteLine(" ID:            " + info.Id);  
          Console.WriteLine(" Enabled:       " + voice.Enabled);  
          if (info.SupportedAudioFormats.Count != 0)  
          {  
            Console.WriteLine( " Audio formats: " + AudioFormats);  
          }  
          else  
          {  
            Console.WriteLine(" No supported audio formats found");  
          }  

          string AdditionalInfo = "";  
          foreach (string key in info.AdditionalInfo.Keys)  
          {  
            AdditionalInfo += String.Format("  {0}: {1}\n", key, info.AdditionalInfo[key]);  
          }  

          Console.WriteLine(" Additional Info - " + AdditionalInfo);  
          Console.WriteLine();  
        }  
      }  
      Console.WriteLine("Press any key to exit...");  
      Console.ReadKey();  
    }  
  }  
}  

Remarks

A voice is an installed speech synthesis engine, which is also referred to as a text-to-speech engine or a TTS engine. The SpeechSynthesizer object uses a voice to generate speech from text. The properties of the VoiceInfo object identify a voice and describe its characteristics. The most defining characteristic of a voice is its Culture, which defines the single language that a voice can speak.

The Voice property returns a VoiceInfo object that contains information about the current voice in use by the SpeechSynthesizer. You can also use a VoiceInfo object to get information about any of the voices that are installed on the system, as returned by the GetInstalledVoices() method. See InstalledVoice for more information.
