Property Value



A collection of VoiceInformation objects.


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

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);


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.
