Cobalt Builds AI Voice Wearable Inside Casio F91W
|
5.3
Cobalt embeds an AI voice wearable into a Casio F91W using nRF52840, a PDM mic, IMA ADPCM, BLE 2Mbps and Groq Whisper. It runs 4 months on a CR2016 battery and pairs with a custom voice assistant app.
Scoring Rationale
Niche hardware demonstration shows practical low-power, on-device voice with `Groq Whisper`, valuable for wearable and edge engineers. It is an interesting maker-level advance rather than a broad industry shift.
