SpeechSynthesizer synthesizer = new SpeechSynthesizer();
synthesizer.SetOutputToDefaultAudioDevice();
synthesizer.SelectVoiceByHints(VoiceGender.Female, VoiceAge.Teen, 0, CultureInfo.GetCultureInfo("en-gb"));
synthesizer.SetOutputToWaveStream(audioStream);
//add a space between all characters to spell it out.
