5.使用Siri和Google聽你的指令
5. Let Siri and Google listen for your commands.
iPhone和安卓手機都有免手動操作功能,可以通過語音指令,同它們的虛擬助手說話。你可以對iPhone手機說“Hey Siri”或者說“O.K. Google”,然后說出你的指令。這雖然方便,但這個功能需要你的手機經常收聽這句特別的指令,也需要使用一些電能。
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.
然而如果你的手機支持這種功能,那么禁用它也省不了多少電。Wirecutter使用iPhone 6s Plus和Nexus 6P進行測試,發現在兩個小時時間內,開啟虛擬助手和禁用虛擬助手,所費電量相差無幾。
