You can select a pre-installed voice that will speak in you chosen language.

I'm almost sure that the default language of your computer/server will be used if you don't select any voice.

using (SpeechSynthesizer synthesizer = new SpeechSynthesizer())
{
    synthesizer.SetOutputToDefaultAudioDevice();

    // this
    synthesizer.SelectVoice("ScanSoft Virginie_Dri40_16kHz");

    // or this
    synthesizer.SelectVoiceByHints(VoiceGender.Neutral, VoiceAge.NotSet, 0, CultureInfo.GetCultureInfo("fr-fr"));

    synthesizer.Speak("Bonjour !");
}
