Gemma Translator multilingual interpreter runs locally on Raspberry Pi 5 with the LiteRT runtime

Google engineers built Gemma Translator, an open-source project that runs a fully offline multilingual voice translator on a Raspberry Pi 5 using Google Gemma 4 E2B (2.3B effective / ~5.1B total parameters) and the LiteRT runtime. The system, created with Google Antigravity, requires a Raspberry Pi 5 with 8GB RAM, a display, microphone, speaker, and keyboard, and can interpret speech without cloud access.

Gemma Translator is an open-source project for the Raspberry Pi 5 that acts as a multilingual interpreter running locally without access to the cloud using Google Gemma 4 and LiteRT runtime. It’s a project built by three Google engineers with the help of Google Antigravity. It includes code to run an on-device, fully offline voice translator/interpretor using Gemma 4 E2B 2.3B effective / ~5.1B total parameters with per-layer embeddings and the LiteRT runtime/inference network. The hardware is comprised of a few components: A Raspberry Pi 5 with 8GB of RAM Display – HDMI monitor or touchscreen display such as a 480×320 kiosk display Audio Microphone or USB audio capture interface Speaker or headphone output device Keyboard – The project demonstrated below appears to use a custom PCB AX-4LABS-NEW with a potentiometer and four mechanical keys of which only two are used Optional 3D printed parts for the enclosure Software highlights: ...
