A newly revealed patent application filed by Amazon is raising privacy concerns over an envisaged upgrade to the company's smart speaker systems. 最近公布的亚马逊的专利申请，因为该公司智能音箱系统的预想升级引发了关于隐私问题的担忧。 This change would mean that, by default, the devices end up listening to and recording everything you say in their presence. 这项功能的改变意味着在默认情况下，音箱会监听并记录一切你在它附近所说的话。 Alexa, Amazon's virtual assistant system that runs on the company's Echo series of smart speakers, works by listening out for a 'wakeword' that tells the device to turn on its extended speech recognition systems in order to respond to spoken commands. Alexa是亚马逊用在该公司Echo系列智能音箱上的虚拟辅助系统，它会通过听“唤醒词”来控制音箱开启扩展语音识别系统来对语音指令做出反应。 On Amazon's devices, the wakeword is 'Alexa', but similar systems control how Apple devices work ('Hey Siri') and also Google's ('Hey Google'), not to mention products from other tech companies. 亚马逊音箱的唤醒词是“Alexa”，还有类似的系统控制着苹果设备（“Hey Siri”），谷歌也有（“Hey Google”），很多其他科技公司的产品都有。 In theory, Alexa-enabled devices will only record what you say directly after the wakeword, which is then uploaded to Amazon, where remote servers use speech recognition to deduce your meaning, then relay commands back to your local speaker. |
