Google Creative Lab published gemma-translator, an Apache-2.0 licensed open-source reference project for a fully offline, on-device voice translator. It runs the gemma4-e2b model locally through LiteRT-LM, with Moonshine handling speech-to-text and moonshine-voice handling text-to-speech, a React/Vite frontend built for small 480x320 kiosk displays, and a Python http.server API. The target hardware is a Raspberry Pi 5 with 8GB RAM plus microphone, speaker and display; deploy-pi.sh installs dependencies, registers a systemd unit and autostarts Chromium in kiosk mode on port 3000. The repo also ships STL files for a 3D-printed case and supports two-lane conversation with landscape or vertical keyboard modes. It carries 763 stars and 90 forks, was built with assistance from Google Antigravity, and is explicitly not an officially supported Google product.
