国内是否可以安装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.

您的智能扬声器可以听到人类听不到的声音，这意味着攻击者可能会在您不注意的情况下触发命令。现在正在实验室中进行。

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

这是克雷格·史密斯(Craig S. Smith)，为《纽约时报》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.
在过去的两年中，中国和美国的研究人员已经开始证明，他们可以向苹果的Siri，亚马逊的Alexa和Google的Assistant发送人耳无法检测到的隐藏命令。在大学实验室内部，研究人员已经能够秘密激活智能手机和智能扬声器上的人工智能系统，从而使他们拨打电话号码或打开网站。如果使用不当，该技术可能会被用来解锁门，电汇资金或在线购买东西，而仅仅是通过收音机播放音乐。

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，一辆汽车正在大声播放音乐，并且还无法检测到要求Alexa和Google Home解锁前门。我相信您可以幻想其他情况。

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.

不要惊慌：目前没有证据表明有人在实验室外使用这些技巧，并且Amazon和Google都在研究此类安全问题。如果您担心的话，可以考虑培训Alexa识别语音或为Google Home设置多个帐户-您可以将某些功能限制为仅识别语音。而且，无论您是否担心此问题，您都应该使用PIN来保护Echo上的语音购买。
