写一个win8.1语音识别的时候await总报错

[qq_22540415]

private void Button_Click(object sender, RoutedEventArgs e)
{
// 实例化
SpeechRecognizer sr = new SpeechRecognizer();
// 开始识别
Button btn = (Button)sender;
btn.IsEnabled = false;
SpeechRecognitionResult result = await sr.RecognizeAsync();
// 显示被识别的文本
txtInput.Text = result.Text;
btn.IsEnabled = true;
}

加async即可 private async void Button_Click(object sender, RoutedEventArgs e)
