Gemma Translator

An offline voice translator from a small team at Google Creative Lab that runs Gemma 4 E2B on-device through LiteRT-LM on a Raspberry Pi 5 with 8GB of RAM. Two people face each other at a kiosk, each with their own lane and a rotating language picker; speech is transcribed with Moonshine, translated by Gemma and spoken back in the other person's language with moonshine-voice, with no internet needed after setup. It ships a React front end tuned for 480x320 displays, a Python API server, a one-command script that installs it as a Pi kiosk service, and STL files for a 3D-printed case. Built with Google Antigravity and marked as not an officially supported Google product. Apache-2.0, 1,586 stars, created 3 August.
