Architecture

JCore’s logical stack has four functional layers. Three cross-cutting pieces sit between them: a local network, a storage module and a dialog management module. Everything runs on one infrastructure layer.

​

Perception

Perception turns sound into text and text back into sound. Wyoming is the protocol Home Assistant uses to talk to voice services. Running wake-word detection and speech synthesis as Wyoming services lets them plug into Home Assistant’s voice pipeline.

​

Local VA network

The voice-assistant devices sit on their own network.

​

Context & understanding

This layer is what gives JCore persistent recall. It keeps what the assistant has learned in several forms, each suited to a different kind of lookup. The storage module sits below this layer and connects it to reasoning.

​

Reasoning

The dialog management module sits below this layer and connects it to execution.

Infrastructure

The server that runs the stack: The prototyping boards, including a Jetson Orin Nano for local inference, are listed under Hardware on the overview page.

Not documented yet

• How the modules talk to each other. The storage and dialog management modules are named in the design, but their interfaces aren’t written up.
• Setup. There are no install or configuration instructions yet.
• The hardware build report. It’s planned but not published.
