A future Windows 10 PC with an Intel processor might be able to let its owner wake it up from a low power state just by saying, "Hey Cortana". That's the premise behind Intel's "Wake-on-voice" that was demoed today at the company's annual Intel Developer Forum.

Pocket-lint reports that the technology, which Intel developed in partnership with Microsoft, will allow Cortana in Windows 10 to always be listening, even in a low power mode:

"No need to press a button, no need to boot up manually: the new integrated audio DSP means you can say "Hey Cortana" and get your PC to wake-up from a low power state ready for interaction."

"Brian Krzanich, Intel CEO, took to the stage at IDF 2015 to explain how the "breakthrough in digital audio is always listening and always responding in a real-time way", and that interaction "should feel like two-way conversations we have in our everyday lives".

"Wake-on-voice" will be incorporated inside Intel's processors but there's no word on when that might happen.
