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.

      // 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)
