SpeechSynthesizer.AllVoices Property

Definition

Gets a collection of all installed speech synthesis engines (voices).

C#
public static IReadOnlyList<VoiceInformation> AllVoices { get; }

Property Value

A collection of VoiceInformation objects.

Examples

Here, we show how to select a gender for the voice (VoiceInformation.Gender) by using either the first female voice (VoiceGender) found, or just the default system voice (SpeechSynthesizer.DefaultVoice), if no female voice is found.

C#
using (SpeechSynthesizer synthesizer = new SpeechSynthesizer())
{
    VoiceInformation voiceInfo =
        (
            from voice in SpeechSynthesizer.AllVoices
            where voice.Gender == VoiceGender.Female
            select voice
        ).FirstOrDefault() ?? SpeechSynthesizer.DefaultVoice;

    synthesizer.Voice = voiceInfo;

    // Windows.Media.SpeechSynthesis.SpeechSynthesisStream
    stream = await synthesizer.SynthesizeTextToStreamAsync(text);
}

Remarks

Only Microsoft-signed voices installed on the system can be used to generate speech with a SpeechSynthesizer. Each voice generates synthesized speech in a single language, as spoken in a specific country/region.

By default, a new SpeechSynthesizer object uses the current system voice (call DefaultVoice to find out what the default voice is).

To specify any of the other speech synthesis (text-to-speech) voices installed on the user's system, use the Voice method (to find out which voices are installed on the system, call AllVoices).

If you don't specify a language, the voice that most closely corresponds to the language selected in the Language control panel is loaded.
