Hands Free Activation的意思|示意

Another cool feature of this is the voice activation for hands free phones.

另外一个很酷的特色就是免提电话语音激活。

Eye-tracking could soon be coming to cell phones, allowing hands-free control of mobile devices that goes way beyond voice activation, Technology Review reports.

眼球跟踪技术很快就会应用到手机上，那时移动设备的无手控制就不仅仅是声音激活了， 技术评论报道。

Voice activation is perfect for placing a call; opening the flip lid on a phone is probably the most effective way of answering it (or again using voice activation for hands-free use).

语音激活来打电话就非常理想，打开翻盖手机的盖子来接电话无疑也是最有效的接电话的方式之一，或者用语音激活免提功能。
