UWP语音朗读和语音识别

朗读

//朗读选中文本
private async void OnRead(object sender, RoutedEventArgs e)
{
    string Text2Read = redit.Document.Selection.Text;
    if (Text2Read != "")
    {
        SpeechSynthesizer synthesizer = new SpeechSynthesizer();
        SpeechSynthesisStream stream = await synthesizer.SynthesizeTextToStreamAsync(Text2Read);
        //Me为MediaElement AutoPlay true；
        Me.SetSource(stream,stream.ContentType);
    }
}

识别
