Amazon recently added the ability for users to unlock their smart lock-equipped doors using Alexa. This is a welcome feature, but it does raise some concerns about intruders yelling through windows to tell Alexa to unlock your door. Is this a concern you should worry about, though?
亚马逊最近为用户增加了使用Alexa解锁配备智能锁的门的功能 。 这是一项受欢迎的功能,但确实引起了一些入侵者对通过窗户大喊叫Alexa解锁门的担忧。 不过,这是您应该担心的问题吗?
For starters, the unlock feature for Alexa includes an extra little security measure. When you tell Alexa to unlock a door, you also have to say a four-digit voice code out loud to confirm. So even if an intruder was able to successfully yell through a window at Alexa, they’d need that unique code to actually bypass your lock.
对于初学者来说,Alexa的解锁功能包括一点额外的安全措施。 当您告诉Alexa解锁门时,您还必须大声说出四位数的语音代码以进行确认。 因此,即使入侵者能够成功通过Alexa的窗口大喊大叫,他们也需要唯一的代码才能真正绕过您的锁。
But, I wanted to see if it was possible for Alexa to hear me through windows in the first place. I set up an Echo near my glass patio door and got to work.
但是,我想先看看Alexa是否有可能通过窗户听到我的声音。 我在玻璃露台门附近建立了回声,开始工作。

As you can see in the photo above, I set the Echo near the patio door, but not right next to it—realistically, in most houses, the Echo won’t be directly in front of a window, but rather off to the side somewhere.
如您在上面的照片中看到的,我将Echo设置在露台门附近,但不紧挨着它-实际上,在大多数房屋中,Echo不会直接在窗户前面,而应在侧面某处。
I stepped outside, closed the patio door, and started yelling “Alexa” so many times that the neighbors were probably thinking some girl named Alexa kicked me out of the house and I was making a last-ditch effort to somehow win her back.
我走到外面,关上露台的门,然后大声喊着“ Alexa”,邻居们可能以为是个叫Alexa的女孩把我踢出了屋子,而我正竭尽全力以某种方式赢得她。
Alexa wasn’t having it, though. I even cupped my hands around the glass to try and concentrate the sound, but that didn’t work either—the double-pane glass was doing a great job. It wasn’t until I moved the Echo about 3-4 feet directly in front of the patio door that I finally started to see results. I was able to trigger Alexa about 70% of the time, and was even able to fire off a couple of basic commands like, “What’s the weather?” and “What time is it?”—although it had a harder time deciphering commands than simply responding to hearing its own name.
不过,Alexa没有。 我什至双手托住玻璃杯以尝试集中声音,但是那也不起作用,因为双层玻璃杯做得很好。 直到我将Echo移到露台门前约3-4英尺的地方后,我终于开始看到效果了。 我能够大约70%的时间触发Alexa,甚至还可以触发一些基本命令,例如“天气如何?” 和“现在几点?” —尽管比简单地响应听到自己的名字要花更多的时间来解密命令。

Now it was time for the moment of truth—would I be able to unlock my own front door by yelling at Alexa through a window? It took me a couple of pain-staking tries, but I eventually got it to work. Although it would’ve been more difficult if my wife hadn’t been there to signal to me that, indeed, Alexa heard me correctly. Otherwise, I’d have to rely on the LED light ring atop the Echo and simply guess whether or not it worked.
现在是时候了,我可以通过窗户大喊Alexa来解锁自己的前门吗? 我花了一些艰苦的尝试,但最终我还是成功了。 尽管如果我的妻子不在那儿要向我传达信号的确更加困难,的确,Alexa正确地听了我的话。 否则,我将不得不依靠Echo顶部的LED灯环,然后简单地猜测它是否有效。
So is it possible for someone to activate your Echo from outside? Yes, it’s possible. If you have Alexa sitting close to a window, or maybe if you have single pane glass (or you leave windows cracked open), then it would be easier to manipulate her from outside. But, in most situations, it just isn’t going to work very well.
那么有人可以从外部激活您的Echo吗? 是的,有可能。 如果您将Alexa坐在靠近窗户的地方,或者如果您只有一块窗格玻璃(或者您将窗户裂开了),那么从外面操纵她会更容易。 但是,在大多数情况下,它不能很好地工作。
Plus, even if someone wanted to unlock your smart lock using Alexa, they would need the voice code to do it. So it would be a futile effort from the start.
另外,即使有人想使用Alexa解锁您的智能锁,他们也需要语音代码才能完成。 因此从一开始就将是徒劳的。
