Always-On Listening Mode Proof-of-Concept Demoed on the Nexus 5

Untitled-1

When the Moto X was first announced, many were skeptical about the supposedly flagship device with less than flagship specifications. Then as time went on, it gradually became clear that the Moto X wasn’t exactly about raw hardware specs. Rather, the device’s innovative features were its selling points.

We’ve already seen various Active Display-like implementations for other devices, but for many, the coolest feature of the Moto X is undoubtedly the famous “OK Google Now” wake-up hot word. This lead many to wonder if this same type of functionality could be added to other devices without a massive battery drain. Then came Senior Recognized Developer Xplodwild.

Xplodwild was able to use the dedicated audio processing chip on the Google Nexus 5‘s Snapdragon 800 SoC to handle device wake hot word detection. The results can be seen in the video below.

Since this is only a proof-of-concept, don’t even think of asking for ETAs. However, it’s certainly more than encouraging to see this sort of thing possible. Head over to Xplodwild’s Google+ post and Senior Member barqers‘s XDA discussion thread to learn more.

[Many thanks to my fellow writer Tom for the heads up!]
