Windows 10 - 編程Cortana

Question

我正在嘗試為Cortana編寫一個小應用程序。

我的想法是，我說:(我啟用了“嘿Cortana”功能）

Hey Cortana, Convert 45 degrees to farenheit

然后我在輸出窗口（Visual Studio）中獲得（此刻）日志。 我試着准確地說出這句話，而Cortana完全理解我，但Cortana打開瀏覽器並將其輸入Bing。

為什么？ 我做錯了什么？ 我沒有得到任何語法錯誤。

這是我的代碼：

// commands.xml

<?xml version="1.0" encoding="utf-8"?>
<VoiceCommands xmlns="http://schemas.microsoft.com/voicecommands/1.1">
  <CommandSet xml:lang="en-us" Name="MyCommands_en-us">

    <Example> Convert 45 degrees to farenheit </Example>

    <Command Name ="farenheitToDegrees">
      <Example> 73 farenheit to degrees</Example>
      <ListenFor> {farenheit} farenheit to degrees </ListenFor>
      <Feedback> {farenheit} are ... in degrees </Feedback>

有人能幫助我嗎？

Answer 1

您上面列出的VCD定義文件沒有PhraseTopic或PhraseList來定義花括號中的部分：

 <ListenFor> {farenheit} farenheit to degrees </ListenFor>

我猜你可能想要一個PhraseTopic，因為它允許一個適應各種數字的無約束的聽寫，如下所示：

<PhraseTopic Label="farenheit" Scenario="Dictation">
   <Subject>Temperature</Subject>
</PhraseTopic>

請參閱msdn上的 VCD規范，您可能想要調整Scenario值。 當然，這確實意味着你需要自己處理你所獲得的文本作為farenheit術語，但通常用數字表示的文本以文本'1234'形式出現（但不是在100％的情況下）。

Answer 2

檢查VCD文件的屬性，值應為：構建操作=內容，復制到輸出目錄=始終復制。 無論如何，我希望你注冊了vcd文件：

VoiceCommandService.InstallCommandSetsFromFileAsync(new Uri("ms-appx:///VCD.xml"));

Answer 3

嗯......似乎你已經了解了所有步驟，但仍然缺少某些東西......

這是我對Cortana的前景功能做出的一個例子：

這是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>

創建此定義后，您需要在App Startup中注冊它：

    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);
        }
    }

然后重寫App.OnActivated方法來處理觸發事件的時間：

    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;

我想你錯過了命令的一部分。

你要求Cortana將學位轉換為華氏度，而且程序很混亂，因為你不夠具體。

如果你想讓Cortana從攝氏度轉換到華氏度，你必須告訴它特別攝氏溫度到華氏溫度。
