如何让alexa等待3-4秒等待用户输入，否则继续

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

const WaitIntentHandler = {
  canHandle(handlerInput) {
    return Alexa.getRequestType(handlerInput.requestEnvelope) === 'IntentRequest'
      && Alexa.getIntentName(handlerInput.requestEnvelope) === 'WaitIntent';
  },
  handle(handlerInput) {
    return new Promise((resolve, reject) => {
      setTimeout(() => {
        resolve(handlerInput.responseBuilder.getResponse());
      }, 3000); // 设置等待时间为3秒
    });
  },
};

const skillBuilder = Alexa.SkillBuilders.custom();

exports.handler = skillBuilder
  .addRequestHandlers(
    WaitIntentHandler
  )
  .lambda();
