我正在尝试将自己的响应添加到自定义意图。LaunchRequest 文本有效,但除了 AMAZON.HelpIntent 和其他默认意图之外,我自己的意图没有得到识别。

意图:

{
    "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(从此处找到的 nodejs 教程的改编示例:https ://github.com/alexa/skill-sample-nodejs-fact/blob/en-US/lambda/custom/index.js 我添加了 CurrentBPM 函数和将其添加到底部的 addRequestHandlers。它看起来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。” 它确实说出了剧本中的欢迎词。但是当我问“我现在的心跳有多快”时,它只会回答“对不起,不确定”,而不是说出硬编码的回答。

解决方案是在 LaunchRequest 的响应中添加一行:

.withShouldEndSession(false)

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

多亏了Suneet Patil,我相应地更新了脚本(见下文) 起初只有这样有效:

  • 用户:“Alexa,问问我个人的心跳,我现在的心跳有多快。”
  • 亚历克萨:'75 bpm'

但我无法达到目的:

  • 用户:“Alexa 与我的个人心跳对话”
  • Alexa:“欢迎使用您的个人心脏健康监测器。你想知道什么?'(默认退出技能
  • 用户:“我现在的心跳有多快?”
  • Alexa:“抱歉,我不确定。”

使用下面的新脚本:

/* 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();

这现在有效:

  • 用户:“Alexa 与我的个人心跳对话”
  • Alexa:“欢迎使用您的个人心脏健康监测器。你想知道什么?'
  • 用户:“我现在的心跳有多快?”
  • Alexa:“每分钟 75 次。”(技能保持开放以提出另一个问题)

对于任何请求,如果未提供,则shouldEndSession默认为true. 在您的情况下,对的响应LaunchRequest将没有此shouldEndSession参数并且会话关闭。

尽管您始终可以使用ask-nodejs-sdk shouldEndSession(false)来保持会话保持活动状态,但您不必每次都专门将其设置为 false。相反,更好的方法是reprompt在你的LaunchRequest. 如果您包含reprompt()then,sdk 将自动添加"shouldEndSession": false到您的响应中。

使用您现在的代码,您LaunchRequest将等待 8 秒,如果没有用户响应,会话将关闭。但是,对于CurrentBPMHandlerorHelpHandler你已经包含了一个重新提示,它会在reprompt. 当您期望用户的响应时,包含一个重新提示总是一个好主意。

您的交互模型AMAZON.FallbackIntent定义了一个意图,但您尚未在代码中处理它。这AMAZON.FallbackIntent可以帮助您处理意外的话语,或者当用户说出与您技能中的任何意图无关的内容时。如果没有处理程序,那么它将被您的错误处理程序捕获。将其作为错误处理是没有问题的,但更好的方法是专门为此添加一个处理程序并给出类似“对不起,我不明白,请您改写您的问题”或类似内容的响应。

请在下面进行这些更改。1. 在交互模型中,intent start 只给出与“to start”相同的话语,而不是 current。例如:Alexa,让我的个人心跳开始。

  1. 在您的 lambda 代码中,在 getnewfact 方法中的 lambda 代码中,您忘记将意图的名称从 getnewfactintent 更改为 start。

  2. 要调用 currentbpm 意图,请使用“Alexa,询问我的个人心跳我现在的心跳有多快。

希望这可以帮助。
