我正在尝试为Cortana编写一个小型应用程序。
我的想法是，我说:(我启用了＆＃34;嘿Cortana＆＃34;功能）
Hey Cortana, Convert 45 degrees to farenheit
然后我在输出窗口（Visual Studio）中获取（当前）日志。我试着准确地说出这句话，而Cortana完全理解我，但Cortana打开浏览器并将其输入Bing。
为什么呢？我做错了什么？我没有得到任何语法错误。
这是我的代码：
// commands.xml

有人能帮助我吗？

您上面列出的VCD定义文件没有PhraseTopic或PhraseList来定义大括号中的部分：
<ListenFor> {farenheit} farenheit to degrees </ListenFor>
我猜你可能想要一个PhraseTopic，因为它允许一个适用于各种数字的无约束的听写，如下所示：
<PhraseTopic Label="farenheit" Scenario="Dictation">
<Subject>Temperature</Subject>
</PhraseTopic>
请参阅VCD的here on msdn规范，您可能想要调整Scenario值。这确实意味着你需要自己处理你所获得的文本作为farenheit术语，当然，通常用文本'1234'形式来指示数字的文本（但不是在100％的情况下）。

检查VCD文件的属性，值应为：构建操作=内容，复制到输出目录=始终复制。无论如何，我希望您注册了vcd文件：
VoiceCommandService.InstallCommandSetsFromFileAsync(new Uri("ms-appx:///VCD.xml"));

嗯......似乎你已经理解了所有步骤，但仍然缺少某些东西......
以下是我对Cortana前台功能的一个例子：
这是VCD ......
<?xml version="1.0" encoding="utf-8" ?>
<VoiceCommands xmlns="http://schemas.microsoft.com/voicecommands/1.2">
<CommandSet xml:lang="en-us" Name="HomeControlCommandSet_en-us">
<CommandPrefix>HomeControl</CommandPrefix>
<Example>Control alarm, temperature, light and others</Example>
<Command Name="Activate_Alarm">
<Example>Activate alarm</Example>
<ListenFor>[Would] [you] [please] activate [the] alarm [please]</ListenFor>
<ListenFor RequireAppName="BeforeOrAfterPhrase">Activate alarm</ListenFor>
<ListenFor RequireAppName="ExplicitlySpecified">Activate {builtin:AppName} alarm</ListenFor>
<Feedback>Activating alarm</Feedback>
<Navigate />
</Command>
创建此定义后，您需要在App Startup注册它：
protected async override void OnLaunched(LaunchActivatedEventArgs e)
{
...
// Install the VCD
try
{
StorageFile vcdStorageFile = await Package.Current.InstalledLocation.GetFileAsync(@"HomeControlCommands.xml");
await VoiceCommandDefinitionManager.InstallCommandDefinitionsFromStorageFileAsync(vcdStorageFile);
}
catch (Exception ex)
{
System.Diagnostics.Debug.WriteLine("There was an error registering the Voice Command Definitions", ex);
}
}
然后覆盖App.OnActivated方法来处理触发事件的时间：
protected override void OnActivated(IActivatedEventArgs e)
{
// Handle when app is launched by Cortana
if (e.Kind == ActivationKind.VoiceCommand)
{
VoiceCommandActivatedEventArgs commandArgs = e as VoiceCommandActivatedEventArgs;
SpeechRecognitionResult speechRecognitionResult = commandArgs.Result;
string voiceCommandName = speechRecognitionResult.RulePath[0];
string textSpoken = speechRecognitionResult.Text;
IReadOnlyList<string> recognizedVoiceCommandPhrases;
System.Diagnostics.Debug.WriteLine("voiceCommandName: " + voiceCommandName);
System.Diagnostics.Debug.WriteLine("textSpoken: " + textSpoken);
switch (voiceCommandName)
{
case "Activate_Alarm":
System.Diagnostics.Debug.WriteLine("Activate_Alarm command");
break;

我认为你错过了命令的一部分。
你要求Cortana将学位转换为华氏度，而且程序很混乱，因为你不够具体。
如果你想让Cortana从摄氏度转换到华氏度，你必须告诉它具体摄氏度到华氏度。
