如何在几秒钟内使Alexa倒计时 [英] How to make Alexa countdown in seconds

问题描述

我希望我的技巧能够使Alexa(听觉上)倒计时15秒.我知道我可以在SSML中< break time ="15s"/> .但这是听不到的.我也知道我可以做到:

I want to be able to have alexa (audibly) countdown 15 seconds in my skill. I know I can just <break time="15s" /> in SSML. But that isn't audible. I also know I can just do:

15<break time="1s" />
14<break time="1s" /> 

或者更好(考虑到说这个数字所花费的时间)

or better yet (to account for the time it takes to say the number)

15<break time="0.85s" />
14<break time="0.85s" />

但是，如果我重复多次，那将是大量的重复代码.因此，我可能要编写一个函数，该函数需要一个数秒的时间，并在该间隔内产生SSML倒计时.

But that's going to be a ton of repeated code if I do this many times over. So I'm probably going to write a function that takes in a number and a number of seconds, and produces an SSML countdown in that interval.

但是，在执行此操作之前，我想知道是否存在适当的内置方法?或者，如果某人具有为此功能而已构建的功能?谢谢!!!

Before I do that, however, I was wondering if there's a proper, built-in way of doing this? Or if someone has a function they've already built for this? Thanks!!!

推荐答案

我最终获得了以下功能(在Alexa闲暇的人的帮助下):

I ended up with the following function (with the help of someone on the Alexa slack):

function countDown(numSeconds, breakTime) {
    return Array.apply(null, {length: numSeconds})
        .map((n, i) => {return `<say-as interpret-as="cardinal">${numSeconds-i}</say-as>` })
        .join(`<break time="${breakTime ? breakTime : 0.85}s" />`) + `<break time="${breakTime ? breakTime : 0.85}s" />`;
}
