我现在正在使用 Visual Studio 2017 为 Microsoft Hololens 编写应用程序。目标是使用语音识别语法规范进行语音识别。
我在笔记本电脑上尝试了我的解决方案，它运行良好，但不知何故它不适用于 Hololens 模拟器。问题是最基本的。单词无法识别。编译没有问题，找到 grxml 文件也没有问题。其次，RecognizeWithUIAsync() 窗口不会弹出。
C＃：
// Create an instance of SpeechRecognizer
var speechRecognizer = new SpeechRecognizer(language);
// Load Grammar depending on the selected language
var storageFile = await StorageFile.GetFileFromApplicationUriAsync(new Uri("ms-appx:///Grammar/grammatik_de.grxml"));
var grammarFileConstraint = new SpeechRecognitionGrammarFileConstraint(storageFile, "grammatik");
storageFile = await StorageFile.GetFileFromApplicationUriAsync(new Uri("ms-appx:///Grammar/grammatik_eng.grxml"));
grammarFileConstraint = new SpeechRecognitionGrammarFileConstraint(storageFile, "grammatik");
speechRecognizer.UIOptions.ExampleText = @"Example: Stop all vehicles,Fork higher,Fork lower,Vehicle Forward,Drive Backwards";
// Compile the constraint.
await speechRecognizer.CompileConstraintsAsync();
// Start recognition.
SpeechRecognitionResult speechRecognitionResult = await speechRecognizer.RecognizeWithUIAsync();
//do something with the result
try
{
String action = grammarHandling(speechRecognitionResult);
actionOnSpeechAsync(action);
}
catch (Exception) {
}
