            FrameworkDispatcher.Update();
            effect.Play();
        }

        private void button3_Click(object sender, RoutedEventArgs e)
        {
            LocalME.Source = new Uri("Sounds/translate_tts.mp3", UriKind.Relative);
            LocalME.Position = new TimeSpan(0);
        }

        private void LocalME_MediaOpened(object sender, RoutedEventArgs e)
        {
            LocalME.Play();
