5.使用Siri和Google听你的指令
5. Let Siri and Google listen for your commands.
iPhone和安卓手机都有免手动操作功能,可以通过语音指令,同它们的虚拟助手说话。你可以对iPhone手机说“Hey Siri”或者说“O.K. Google”,然后说出你的指令。这虽然方便,但这个功能需要你的手机经常收听这句特别的指令,也需要使用一些电能。
Both iPhones and Android phones include a hands-free feature for summoning their virtual assistants by speaking voice commands. You can just say “Hey Siri” to the iPhone or “O.K. Google” and then speak your request or command. While convenient, this feature requires your phone to constantly listen for that special phrase, which uses some power.
然而如果你的手机支持这种功能,那么禁用它也省不了多少电。Wirecutter使用iPhone 6s Plus和Nexus 6P进行测试,发现在两个小时时间内,开启虚拟助手和禁用虚拟助手,所费电量相差无几。
