亚历克斯不承认意图

Question

我正在尝试将自己的响应添加到自定义意图中。LaunchRequest文本有效，但是除了AMAZON.HelpIntent和其他默认意图之外，我自己的意图未被识别。

目的：

{
    "interactionModel": {
        "languageModel": {
            "invocationName": "my personal heartbeat",
            "intents": [
                {
                    "name": "AMAZON.FallbackIntent",
                    "samples": []
                },
                {
                    "name": "AMAZON.CancelIntent",
                    "samples": []
                },
                {
                    "name": "AMAZON.HelpIntent",
                    "samples": []
                },
                {
                    "name": "AMAZON.StopIntent",
                    "samples": []
                },
                {
                    "name": "start",
                    "slots": [],
                    "samples": [
                        "Talk to my personal heartbeat"
                    ]
                },

                {
                    "name": "currentbpm",
                    "slots": [],
                    "samples": [
                        "what's my current BPM",
                        "how fast is my heart beating right now",
                        "How many beats per minute is my heart making at the moment"
                    ]
                }

            ],
            "types": []
        }
    }
}

index.js（来自nodejs教程的自适应示例，位于此处：https : //github.com/alexa/skill-sample-nodejs-fact/blob/en-US/lambda/custom/index.js 我添加了CurrentBPM函数并将其添加到底部的addRequestHandlers中，它看起来要匹配的意图名称是上面列表中的currentbpm意图。

当我调用该技能时：“ Alexa开始我的个人心跳。” 它确实会说出脚本中的欢迎词。但是，当我问“现在我的心跳多快”时，它只会回答“对不起，不确定”，而不是说出硬编码的回答。

Answer 1

解决方案是在LaunchRequest中的响应中添加一行：

.withShouldEndSession(false)

如果不添加，则默认设置为true，因此该技能将在给出第一个响应（欢迎意图）后立即结束。请参阅文档：https : //ask-sdk-for-nodejs.readthedocs.io/en/latest/Response-Building.html

多亏了Suneet Patil，我才相应地更新了脚本（见下文）。

• 用户：“ Alexa，问一下我的个人心跳，现在我的心脏跳动有多快。”
• Alexa：“ 75 bpm”

但是我无法达到目的：

• 用户：“ Alexa与我的心跳对话”
• Alexa：欢迎使用您的个人心脏健康监测器。您想知道什么？'（默认退出技能）
• 用户：“我的心脏现在跳动有多快？”
• Alexa：“对不起，我不确定。”

使用以下新脚本：

/* eslint-disable  func-names */
/* eslint-disable  no-console */

const Alexa = require('ask-sdk');

const GetNewFactHandler = {
  canHandle(handlerInput) {
    const request = handlerInput.requestEnvelope.request;
    return request.type === 'LaunchRequest'
      || (request.type === 'IntentRequest'
        && request.intent.name === 'start');
  },
  handle(handlerInput) {
    const speechOutput = "Welcome to your personal heart health monitor. What would you like to know?";

    return handlerInput.responseBuilder
      .speak(speechOutput)
      .withSimpleCard(speechOutput)
      .withShouldEndSession(false)
      .getResponse();

  },
};

const CurrentBPMHandler = {
  canHandle(handlerInput) {
    const request = handlerInput.requestEnvelope.request;
    return request.type === 'IntentRequest'
      && request.intent.name === 'currentbpm';
  },
  handle(handlerInput) {
    return handlerInput.responseBuilder
      .speak('seventy five bpm')
      .reprompt('seventy five bpm')
      .getResponse();
  },
};


const HelpHandler = {
  canHandle(handlerInput) {
    const request = handlerInput.requestEnvelope.request;
    return request.type === 'IntentRequest'
      && request.intent.name === 'AMAZON.HelpIntent';
  },
  handle(handlerInput) {
    return handlerInput.responseBuilder
      .speak(HELP_MESSAGE)
      .reprompt(HELP_REPROMPT)
      .getResponse();
  },
};

const ExitHandler = {
  canHandle(handlerInput) {
    const request = handlerInput.requestEnvelope.request;
    return request.type === 'IntentRequest'
      && (request.intent.name === 'AMAZON.CancelIntent'
        || request.intent.name === 'AMAZON.StopIntent');
  },
  handle(handlerInput) {
    return handlerInput.responseBuilder
      .speak(STOP_MESSAGE)
      .getResponse();
  },
};

const SessionEndedRequestHandler = {
  canHandle(handlerInput) {
    const request = handlerInput.requestEnvelope.request;
    return request.type === 'SessionEndedRequest';
  },
  handle(handlerInput) {
    console.log(`Session ended with reason: ${handlerInput.requestEnvelope.request.reason}`);

    return handlerInput.responseBuilder.getResponse();
  },
};

const ErrorHandler = {
  canHandle() {
    return true;
  },
  handle(handlerInput, error) {
    console.log(`Error handled: ${error.message}`);

    return handlerInput.responseBuilder
      .speak('Sorry, an error occurred.')
      .reprompt('Sorry, an error occurred.')
      .getResponse();
  },
};

const HELP_MESSAGE = 'You can say tell me a space fact, or, you can say exit... What can I help you with?';
const HELP_REPROMPT = 'What can I help you with?';
const STOP_MESSAGE = 'Goodbye!';


const skillBuilder = Alexa.SkillBuilders.standard();

exports.handler = skillBuilder
  .addRequestHandlers(
    GetNewFactHandler,
    CurrentBPMHandler,
    HelpHandler,
    ExitHandler,
    SessionEndedRequestHandler
  )
  .addErrorHandlers(ErrorHandler)
  .lambda();

现在可以使用：

• 用户：“ Alexa与我的心跳对话”
• Alexa：欢迎使用您的个人心脏健康监测器。你想知道什么？'
• 用户：'我的心现在跳多快？
• Alexa：“晚上七十五点。”（技能保持开放状态，问另一个问题）
