對於我第一個UWP應用程序項目，我想構建一個帶語音識別的小型測試程序。UnauthorizedAccessException或如何爲UWP應用程序啓用Microfone
通過一些教程Searchin的後，我想出了下面的代碼：
private async void initSpeechParts() {
try {
if (_recognizer == null) {
_recognizer = new SpeechRecognizer();
var lang= _recognizer.CurrentLanguage;
var functionGrammar = new SpeechRecognitionTopicConstraint(SpeechRecognitionScenario.Dictation, "Functioncall");
_recognizer.UIOptions.AudiblePrompt = "Give me the name of a Function";
_recognizer.UIOptions.ExampleText = "Function A";
_recognizer.Constraints.Add(functionGrammar) ;
await _recognizer.CompileConstraintsAsync();
}
try {
// Start recognition.
SpeechRecognitionResult speechRecognitionResult = await _recognizer.RecognizeWithUIAsync();
var recognizedText = speechRecognitionResult.Text;
recognizedText = removetokens(recognizedText);
callTestfunction(recognizedText);
} catch (Exception ex2) {
var ee = ex2.Message;
throw;
}
} catch (Exception ex) {
//Check if user has approved the privacy policy
const uint HresultPrivacyStatementDeclined = 0x80045509;
if ((uint)ex.HResult == HresultPrivacyStatementDeclined)
{
var messageDialog = new Windows.UI.Popups.MessageDialog(
"You must accept the speech privacy policy to continue", "Speech Exception");
messageDialog.ShowAsync().GetResults();
}
}
}
我本規範當前的問題，就是在那裏說行：
SpeechRecognitionResult speechRecognitionResult = await _recognizer.RecognizeWithUIAsync();
我總是未經授權的訪問例外。在Google上閱讀了一些帖子之後，我認爲這可能是因爲應用程序對我的麥克風有些問題。那麼，如何爲我的應用程序啓用麥克風？
