Cortana 回复而不是应用程序启动

Question

好的，我有一个支持 Cortana 的应用程序。我有一些命令可以导航到特定页面。但在某些情况下，我只想提供回复（文本或由 Cortana 发音）而不是启动整个应用程序。有什么办法吗？

例如，当您询问 Cortana "What is capital of USA?" 时，她只会回复您 "Washington"。我想做这样的事情。

看看这个 tutorial 的底部，它详细说明了如何设置她所说和显示的内容。

基本上你需要有一个从语音命令运行的后台任务，然后在执行期间你需要创建一个 VoiceCommandUserMessage.

使用 taskInstance.TriggerDetails

获取 VoiceServiceConnection

    voiceServiceConnection = 
      VoiceCommandServiceConnection.FromAppServiceTriggerDetails(
        triggerDetails);

等待语音命令完成

    VoiceCommand voiceCommand = await voiceServiceConnection.GetVoiceCommandAsync();

然后添加

VoiceCommandUserMessage userMessage = new VoiceCommandUserMessage();
userMessage.DisplayMessage = "Here’s your trip.";
userMessage.SpokenMessage = "Your trip to Vegas is on August 3rd.";

将其包装在响应中

var response = 
  VoiceCommandResponse.CreateResponse(
    userMessage);

最后，让Cortana显示出来：

await voiceServiceConnection.ReportSuccessAsync(response);

据我了解，这仅适用于 Windows 10 个应用程序。

Windows 应用程序允许您在前台和后台与 Cortana 交互。我相信背景就是你要找的：

首先您需要创建一个 XML 文件来重新设置您的 VCD（语音命令定义）。这是您声明要使用的命令的地方：

<?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="CheckTemperature">
      <Example>Check temperature</Example>
      <ListenFor>check [current] temperature</ListenFor>
      <Feedback>Checking temperature</Feedback>
      <VoiceCommandService Target="VoiceCommandService" />
    </Command>

  </CommandSet>
</VoiceCommands>

在App.xaml.cs里面App.OnLaunched注册VCD后:

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);
    }
}

之后，您需要创建一个新的 Windows Runtime Component 项目并创建一个 class 实现 IBackgroundTask:

public sealed class HomeControlVoiceCommandService : IBackgroundTask
{
    private VoiceCommandServiceConnection voiceServiceConnection;
    private BackgroundTaskDeferral serviceDeferral;

    public async void Run(IBackgroundTaskInstance taskInstance)
    {
        // Create the deferral by requesting it from the task instance
        serviceDeferral = taskInstance.GetDeferral();

        AppServiceTriggerDetails triggerDetails = taskInstance.TriggerDetails as AppServiceTriggerDetails;

        if (triggerDetails != null && triggerDetails.Name.Equals("VoiceCommandService"))
        {
            voiceServiceConnection = VoiceCommandServiceConnection.FromAppServiceTriggerDetails(triggerDetails);

            VoiceCommand voiceCommand = await voiceServiceConnection.GetVoiceCommandAsync();

            // Perform the appropriate command depending on the operation defined in VCD
            switch (voiceCommand.CommandName)
            {
                case "CheckTemperature":
                    VoiceCommandUserMessage userMessage = new VoiceCommandUserMessage();
                    userMessage.DisplayMessage = "The current temperature is 23 degrees";
                    userMessage.SpokenMessage = "The current temperature is 23 degrees";

                    VoiceCommandResponse response = VoiceCommandResponse.CreateResponse(userMessage, null);
                    await voiceServiceConnection.ReportSuccessAsync(response);
                    break;

                default:
                    break;
            }
        }

        // Once the asynchronous method(s) are done, close the deferral
        serviceDeferral.Complete();
    }
}

不要忘记添加这个新项目作为主要项目的参考。此外，您需要在 Package.appxmanifest:

中注册服务

<Extensions>
<uap:Extension Category="windows.appService" EntryPoint="CortanaComponent.HomeControlVoiceCommandService">
  <uap:AppService Name="VoiceCommandService" />
</uap:Extension>
</Extensions>

这应该有效！
