Voice unlock coming with Microsoft's always-on virtual assistant Cortana

Qualcomm's Snapdragon 800 supports this function, but given that Motorola made a dedicated X8 chipset with a low-power processor specifically for that task, it will be interesting to see how Microsoft has achieved the power-sipping functionality with an off-the-shelve silicon.

The second part, and that's where exclusivity jumps in, is that Cortana will allow you to unlock the phone only with your voice, which for every person is as unique as your fingerprints. Again, it will be interesting to see how Microsoft would have done it, if true. We can imagine a beefy Snapdragon 800 will be up to the task to analyze all the intricacies of your vocal cords in a split second, but what about older handsets, how much Cortana are they going to get?

In any case, Microsoft is said to be in the final testing phases for its own voice-controlled assistant, and will have the development interface by Christmas. Yep, that means Cortana is meant to be open, and will work with 3rd party apps from various developers, which would no doubt make it much more useful. What do you think about this eventual voice unlock function - better than a fingerprint unlock, or a gimmick you are not likely to use on a regular basis?
