AI voice companion

A compact, battery-powered AI device for voice conversation with on-screen feedback. After a one-time Wi‑Fi setup from a phone browser, the user presses the side button or wheel, speaks, and the device answers through its speaker and display. It handles music, stories, information queries and smart control, using existing cloud speech and language services.
