Cortana 未注册应用程序的语音命令

Question

我正在努力让 Cortana 与后台应用程序服务交互。 Cortana 正在使用一个语音命令集，但当我尝试来自不同命令集的任何语音命令时，它只会在 Bing 中打开搜索。

关于可能导致它的原因或更改命令以使其更好地与 Cortana 一起工作的任何建议？

不起作用的命令集：

<Command Name="SetTemperatureDefault">
  <Example> change the temperature to 72 degrees </Example>
  <ListenFor RequireAppName="BeforeOrAfterPhrase"> set [the] temperature to {Temperature} degrees </ListenFor>
  <ListenFor RequireAppName="BeforeOrAfterPhrase"> change [the] temperature to {Temperature} degrees </ListenFor>
  <ListenFor RequireAppName="BeforeOrAfterPhrase"> increase [the] temperature to {Temperature} </ListenFor>
  <ListenFor RequireAppName="BeforeOrAfterPhrase"> decrease [the] temperature to {Temperature} </ListenFor>
  <ListenFor RequireAppName="BeforeOrAfterPhrase"> set to {Temperature} degrees </ListenFor>
  <ListenFor RequireAppName="BeforeOrAfterPhrase"> change to {Temperature} degrees </ListenFor>
  <ListenFor RequireAppName="BeforeOrAfterPhrase"> increase to {Temperature} degrees </ListenFor>
  <ListenFor RequireAppName="BeforeOrAfterPhrase"> decrease to {Temperature} degrees </ListenFor>
  <ListenFor RequireAppName="BeforeOrAfterPhrase"> set temp to {Temperature} degrees </ListenFor>
  <ListenFor RequireAppName="BeforeOrAfterPhrase"> change temp to {Temperature} degrees </ListenFor>
  <Feedback> Changing temperature... </Feedback>
  <VoiceCommandService Target="CozyVoiceCommandService" />
</Command>

Answer 1

首先保证你的VCD在app初始化时已经正确安装。确保它没有给出任何异常。

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，由于您正在使用 {Temperature} 命令，因此您需要使用 PhraseTopic 在列出所有 Command.

之后

    ...
    <Command Name="SetTemperatureDefault">
      <Example> change the temperature to 72 degrees </Example>
      <ListenFor RequireAppName="BeforeOrAfterPhrase"> set [the] temperature to {Temperature} degrees </ListenFor>
      <ListenFor RequireAppName="BeforeOrAfterPhrase"> change [the] temperature to {Temperature} degrees </ListenFor>
      <ListenFor RequireAppName="BeforeOrAfterPhrase"> increase [the] temperature to {Temperature} </ListenFor>
      <ListenFor RequireAppName="BeforeOrAfterPhrase"> decrease [the] temperature to {Temperature} </ListenFor>
      <ListenFor RequireAppName="BeforeOrAfterPhrase"> set to {Temperature} degrees </ListenFor>
      <ListenFor RequireAppName="BeforeOrAfterPhrase"> change to {Temperature} degrees </ListenFor>
      <ListenFor RequireAppName="BeforeOrAfterPhrase"> increase to {Temperature} degrees </ListenFor>
      <ListenFor RequireAppName="BeforeOrAfterPhrase"> decrease to {Temperature} degrees </ListenFor>
      <ListenFor RequireAppName="BeforeOrAfterPhrase"> set temp to {Temperature} degrees </ListenFor>
      <ListenFor RequireAppName="BeforeOrAfterPhrase"> change temp to {Temperature} degrees </ListenFor>
      <Feedback> Changing temperature... </Feedback>
      <VoiceCommandService Target="CozyVoiceCommandService" />
    </Command>

    <PhraseTopic Label="Temperature" />
  </CommandSet>
</VoiceCommands>

我已经在这里测试过了，效果非常好。
