UWP 连续语音识别

Question

我正在使用 UWP 创建一个智能镜像应用程序，我希望用户使用他们的声音来控制应用程序。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，但我只想当应用程序听到关键词 - "Jason"时，它会开始将语音转换为文本(我称我的智能镜子Jason(为："Jason，给我看一些新闻"，因为之后我会将文本按摩传递给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;
});
}

Answer 1

如果你只想使用"Jason"作为触发器，你可以添加

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