SpeechSynthesizer.GetInstalledVoices Method

Returns all of the installed speech synthesis (text-to-speech) voices.

Namespace:  System.Speech.Synthesis
Assembly:  System.Speech (in System.Speech.dll)

public ReadOnlyCollection<InstalledVoice> GetInstalledVoices()

Return Value

Type: System.Collections.ObjectModel.ReadOnlyCollection<InstalledVoice>
Returns a read-only collection of the voices currently installed on the system.

A voice is an engine for speech synthesis (text-to-speech or TTS) that is installed on the system.

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();
    }
  }
}
