AMAZON.FallbackIntent不工作ask
我正在尝试使用亚马逊内置功能对我的自定义Alexa技能进行越界查询。 Alexa可以使用“AMAZON.FallbackIntent”这样，我在这里找到了基本设置：
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，我已经设置了一个“en-GB.json”和“en-US.json”，结构如下：
"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Fallback之外，所有内置意图都可以正常工作。以下是该技能的index.js片段的示例：
const Alexa = require('ask-sdk');
const dbHelper = require('./helpers/dbHelper');

启动技能后，技能执行：
speechText
我尝试说出天气是什么，技能忽略了输入，只执行：
repromptText
然后，如果我再次要求天气，它只会关闭技能......
我怎么能为英语模型做这个工作？
回答如下：在LanunchRequest处理程序中发送speechText后，您的会话即将结束。会议结束时，Alexa不知道你是在试图通过说“天气怎么样？”来调用你的技能？因此不会调用您的后备处理程序。
使用withShouldEndSession(false)它将保持会话打开，任何不正确的输入将在您的Fallback处理程序中出现。
下面的代码应该工作。
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();
}
};
