While asking Cortana various questions on Windows Phone 8.1 is natural, the way in which one enables the personal voice assistant isn't quite as fluid. Users need to press down on the Search key or press the Live Tile and microphone before Cortana enables, and while it's not difficult there are better solutions available. One of the solutions is passive-voice activation, which is something users of the Xbox One with Kinect should know. Passive-voice activation allows users to engage the AI or system simply by using their voice. Likewise, the Motorola Moto X with Android can also activated by explicitly stating 'Ok, Google Now.' The phone will then come awake, letting users make appointments, starting their music, or sending a text message without ever touching the phone.

Although Cortana is still in its beta stage, many are curious as to when passive-voice activation will arrive, as it seems like the next reasonable step. Marcus Ash, Group Program Manager for Cortana on Windows Phone, has once again taken to Twitter to tease the feature: "Something to think about as we design voice activation for #Cortana. Don't want Jesse sending texts on your behalf." Ash is referring to the new Xbox One commercial featuring 'Breaking Bad' Star Aaron Paul. In the ad, Paul says 'Xbox On' and for anyone with an Xbox One and Kinect system, their system may accidentally turn on as a result. Clearly, this is a downside to passive-voice activation and something that Ash and his team are taking into consideration when further designing Cortana. Of course, the big surprise there is that Ash just admitted that Microsoft is actively developing voice activation. That news is not necessarily surprising, but it is reassuring.
