Overview

Headless Pi 5 with a 10" touchscreen auto-transcribes landline calls (Fi3001A tap) and room conversation (TONOR mic), switching sources when a call rings—built as an unattended accessibility appliance with open MIT code.

How it works

A USB telephone recorder taps the landline and a conference mic covers the room; the Pi 5 transcribes in near real time and shows large captions.
