【问题描述】：

windows cortana 的新更新具有始终监听模式，类似于 Google 的“OK Google”命令，即使手机处于待机状态，用户也可以激活 Cortana。是“嘿 Cortana”。

以同样的方式，当我的应用程序启动时，我希望有一个始终监听模式，它可以只监听特定的单词集（就像“嘿 Cortana”），并相应地响应它。

【解决方案1】：

您可以使用适用于 Windows 10 的 ContinuousRecognitionSession 实现连续听写。

private SpeechRecognizer speechRecognizer;
private CoreDispatcher dispatcher;
private StringBuilder dictatedTextBuilder;

this.dispatcher = CoreWindow.GetForCurrentThread().Dispatcher;
this.speechRecognizer = new SpeechRecognizer();
SpeechRecognitionCompilationResult result =

await speechRecognizer.CompileConstraintsAsync();
speechRecognizer.ContinuousRecognitionSession.ResultGenerated +=
ContinuousRecognitionSession_ResultGenerated;

private async void ContinuousRecognitionSession_ResultGenerated(
SpeechContinuousRecognitionSession sender,
SpeechContinuousRecognitionResultGeneratedEventArgs args)
{

if (args.Result.Confidence == SpeechRecognitionConfidence.Medium ||
  args.Result.Confidence == SpeechRecognitionConfidence.High)
  {
    dictatedTextBuilder.Append(args.Result.Text + " ");

    await dispatcher.RunAsync(CoreDispatcherPriority.Normal, () =>
    {
      dictationTextBox.Text = dictatedTextBuilder.ToString();
      btnClearText.IsEnabled = true;
    });
  }
else
{
  await dispatcher.RunAsync(CoreDispatcherPriority.Normal, () =>
    {
      dictationTextBox.Text = dictatedTextBuilder.ToString();
    });
}
}

这里是完整的example
