Nexus 5 has low-core functionality for “always-on listening” voice recognition


If you didn’t know already, the Nexus 5 actually has a low-power audio processor for “always-on” listening (OK, Google) functionality. However, due to the limited functionality of the feature and its closed-source nature, it only works on the home screen and not when the device is asleep.

However, developer Guillaume Lesniak from the OmniROM team has managed to access the¬†dedicated low-power audio core on the Snapdragon 800 chip to make use of this feature. The functionality is only a proof of concept for now, and although we could see it in later ROMs, it is unlikely because of Qualcomm’s re-distribution licensing issues. Hit the break for a video of the feature.
