просто проиграйте 5-10 секунд аудио, затем автоматически остановите умение Alexa

Question

У меня есть один аудио навык в Алексе. Но есть одна проблема: проигрывать аудио всего несколько секунд, а затем останавливать.

мой код:

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

let currentAudioNum = 0;
let skill;
const STREAMS = [
  {
.........
  },
  {
.........
  },
];

const PlayStreamIntentHandler = {
  canHandle(handlerInput) {
    return handlerInput.requestEnvelope.request.type === 'LaunchRequest' ||
        (handlerInput.requestEnvelope.request.type === 'IntentRequest'
        && handlerInput.requestEnvelope.request.intent.name === 'PlayStreamIntent') ||
        (handlerInput.requestEnvelope.request.type === 'IntentRequest'
        && handlerInput.requestEnvelope.request.intent.name === 'AMAZON.ResumeIntent');
  },
  handle(handlerInput) {

    let stream = STREAMS[currentAudioNum];

    handlerInput.responseBuilder
      .speak(`starting swaminarayan kirtan bhakti`)
      .addAudioPlayerPlayDirective('REPLACE_ALL', stream.url, stream.token, 0, null, stream.metadata);

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

const PlayNextStreamIntentHandler = {
  canHandle(handlerInput) {
    return handlerInput.requestEnvelope.request.type === 'IntentRequest'
      && handlerInput.requestEnvelope.request.intent.name === 'AMAZON.NextIntent';
  },
  handle(handlerInput) {

    currentAudioNum = currentAudioNum + 1;
    let stream = STREAMS[currentAudioNum];

    handlerInput.responseBuilder
      .addAudioPlayerPlayDirective('REPLACE_ALL', stream.url, stream.token, 0, null, stream.metadata);

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

const PlayPrevStreamIntentHandler = {
  canHandle(handlerInput) {
    return handlerInput.requestEnvelope.request.type === 'IntentRequest'
      && handlerInput.requestEnvelope.request.intent.name === 'AMAZON.PreviousIntent';

  handle(handlerInput) {

    currentAudioNum = currentAudioNum - 1;
    let stream = STREAMS[currentAudioNum];

    handlerInput.responseBuilder

    const speechText = 'This skill just plays an audio stream when it is started. It does not have any additional functionality.';

      .speak(speechText)
      .reprompt(speechText)
