What This Reference Design Is
A voice terminal that talks back and can be cut off mid-sentence.
A microphone array and a speaker attach to the board. It listens, answers, and stops as soon as you speak over it.
Listening and speaking both run on the device. Only the conversation model is a choice: a cloud endpoint, or a model kept on the board.
The language is fixed at deploy time, not guessed sentence by sentence. A language the board cannot serve is refused rather than degraded.
Runs on RK3576, RK3588, Jetson Orin Nano 8GB / Orin NX 16GB and reComputer R2000 series. The microphone must have hardware echo cancellation.
