我正在尝试使用 Amazon 内置功能对我的自定义 Alexa 技能进行越界查询。Alexa 可以为此使用“AMAZON.FallbackIntent”,我在这里找到了基本设置: https ://developer.amazon.com/it/blogs/alexa/post/f6bb7c54-de0d-4abe-98c3-cf3fc75c32f8/how -to-add-fallbackintent-handling-to-your-alexa-skill

现在,所有“en”语言环境都可以使用此功能,无论如何,经过多次尝试,我已经设置了具有相同结构的“en-GB.json”和“en-US.json”,如下所示:

"intents": [
            {
                "name": "AMAZON.FallbackIntent",
                "samples": []
            },
            {
                "name": "AMAZON.CancelIntent",
                "samples": []
            },
            {
                "name": "AMAZON.HelpIntent",
                "samples": [
                    "I don't know",
                    "What can you do",
                    "What are you capable of",
                    "What is this",
                    "help"
                ]
            },
            {
                "name": "AMAZON.StopIntent",
                "samples": []
            },

除了后备意图之外,所有内置意图都可以正常工作。以下是该技能的 index.js 片段示例:

启动技能后,技能执​​行:

语音文本

为此,我尝试说天气如何,该技能会忽略该输入并仅执行:

提示文本

然后如果我再次询问天气,它只会关闭技能......

我怎样才能使这两种英语语言模型都起作用?

在 LanunchRequest 处理程序中发送您的语音文本后,您的会话将立即结束。会话结束时,Alexa 并不知道您正试图通过说“天气怎么样?”来调用您的技能。因此不会调用您的后备处理程序。

使用withShouldEndSession(false)它会使会话保持打开状态,并且任何不正确的输入都会出现在您的后备处理程序中。

下面的代码应该可以工作。

const LaunchRequestHandler = 
{ 
    canHandle(handlerInput) {
        const request = handlerInput.requestEnvelope.request;
        return request.type === 'LaunchRequest';
    },
    handle(handlerInput) {
        const speechText = 'Welcome to the X ' + '&' + 'Y Customer Service, my name is Natalia, how may I help you today?';
        const repromptText = 'What would you like to do? You can say HELP to get available options';

        return handlerInput.responseBuilder
        .speak(speechText)
        .withShouldEndSession(false) 
        .reprompt(repromptText)
        .getResponse();
    }
};
