UWP 连续语音识别

Question

我正在使用 UWP 创建智能镜像应用程序，我希望用户使用他们的语音来控制该应用程序。到目前为止，我做了一个简单的程序来测试语音识别，它可以工作，但我希望只有当应用程序听到关键字-"Jason"时，它才会开始将语音转换为文本（我叫我的智能mirror Jason) 喜欢："Jason, show me some news"，因为之后我会将文本消息传递给 LUIS 函数。如果句子不是以 "Jason" 开头，则应用程序不会将其转换为文本。我应该怎么做才能实现它？ '

    private SpeechRecognizer contSpeechRecognizer;
    private CoreDispatcher dispatcher;

    protected async override void OnNavigatedTo(NavigationEventArgs e)
    {
        dispatcher = CoreWindow.GetForCurrentThread().Dispatcher;
        contSpeechRecognizer = new Windows.Media.SpeechRecognition.SpeechRecognizer();
        await contSpeechRecognizer.CompileConstraintsAsync();  
        contSpeechRecognizer.ContinuousRecognitionSession.ResultGenerated +=ContinuousRecognitionSession_ResultGenerated;
        contSpeechRecognizer.ContinuousRecognitionSession.AutoStopSilenceTimeout = TimeSpan.FromDays(1);
        contSpeechRecognizer.ContinuousRecognitionSession.Completed += ContinuousRecognitionSession_Completed;   
        await contSpeechRecognizer.ContinuousRecognitionSession.StartAsync();
    }

    private async void ContinuousRecognitionSession_Completed(SpeechContinuousRecognitionSession sender, SpeechContinuousRecognitionCompletedEventArgs args)
    {
        await contSpeechRecognizer.ContinuousRecognitionSession.StartAsync();
    }

    private async void ContinuousRecognitionSession_ResultGenerated( SpeechContinuousRecognitionSession sender, SpeechContinuousRecognitionResultGeneratedEventArgs args)
    {           
        await dispatcher.RunAsync(CoreDispatcherPriority.Normal, () =>
        {  
            SpeechResult.Text = args.Result.Text;
        });
    }

如果您只想使用 "Jason" 作为触发器，您可以只添加

if(speechResult.Contains("Jason")||speechResult.Contains("jason"))
{//Pass the Result to LUIS}
