國內是否可以安裝alexa

Your smart speaker can hear sounds that humans can’t, meaning attackers could hypothetically trigger a command without you noticing. It’s happening in labs right now.

您的智能揚聲器可以聽到人類聽不到的聲音，這意味著攻擊者可能會在您不注意的情況下觸發命令。 現在正在實驗室中進行。

Here’s Craig S. Smith, writing for the New York Times:

這是克雷格·史密斯(Craig S. Smith)，為《紐約時報》撰稿：

Over the last two years, researchers in China and the United States have begun demonstrating that they can send hidden commands that are undetectable to the human ear to Apple’s Siri, Amazon’s Alexa and Google’s Assistant. Inside university labs, the researchers have been able to secretly activate the artificial intelligence systems on smartphones and smart speakers, making them dial phone numbers or open websites. In the wrong hands, the technology could be used to unlock doors, wire money or buy stuff online—simply with music playing over the radio.

在過去的兩年中，中國和美國的研究人員已經開始證明，他們可以向蘋果的Siri，亞馬遜的Alexa和Google的Assistant發送人耳無法檢測到的隱藏命令。 在大學實驗室內部，研究人員已經能夠秘密激活智能手機和智能揚聲器上的人工智能系統，從而使他們撥打電話號碼或打開網站。 如果使用不當，該技術可能會被用來解鎖門，電匯資金或在線購買東西，而僅僅是通過收音機播放音樂。

Imagine a car loudly playing music that’s also undetectably asking Alexa and Google Home to unlock the front door. I’m sure you can dream up other scenarios.

想象一下，一輛汽車正在大聲播放音樂，并且還無法檢測到要求Alexa和Google Home解鎖前門。 我相信您可以幻想其他情況。

Don’t panic: there’s no evidence anyone is using these tricks outside of the lab right now, and both Amazon and Google are working on security questions like this. If you’re concerned, consider training Alexa to recognize your voice or setting up multiple accounts for Google Home—you can limit certain functionality to only recognized voices. And you should probably PIN protect voice purchasing on your Echo, regardless of whether you’re worried about this or not.

不要驚慌：目前沒有證據表明有人在實驗室外使用這些技巧，并且Amazon和Google都在研究此類安全問題。 如果您擔心的話，可以考慮培訓Alexa識別語音或為Google Home設置多個帳戶-您可以將某些功能限制為僅識別語音。 而且，無論您是否擔心此問題，您都應該使用PIN來保護Echo上的語音購買。
