Always-Listening Device
A wearable device capable of continuously listening to ambient audio. It typically must run a low-power wake-word detection model locally, uploading audio to the cloud for processing after being woken, and its microphone can hardly ever be truly turned off.
Timeline (last 90 days)
For always-on wearable devices to achieve "wake at any time", they usually need to run a low-power wake-word detection model locally and upload audio to the cloud for further processing after waking, and the microphone can hardly ever be truly turned off.
Always-listening devices usually adopt a layered processing architecture: a low-power wake word detection module on the device, which activates the full audio capture and upload process only after detecting the trigger word.
