Gemma Translator: Offline AI Voice Translator on Raspberry Pi
Google Creative Lab published an open-source voice translator that runs Gemma 4 entirely on-device — no internet required, on a Raspberry Pi 5 with a small screen.
Google Creative Lab (the experimental arm of Google) built an open-source voice translator that runs Google's Gemma 4 model entirely locally using the LiteRT-LM runtime — no internet connection needed after setup. The device runs on a Raspberry Pi 5 with a small touchscreen: it captures speech, transcribes it, translates with Gemma 4, and speaks the result aloud in the other person's language. The full source code, deployment scripts, and even 3D-print files for the case are included.
Why a vibe-coder should care
For anyone who needs private offline translation — on trips, in areas with poor connectivity, or in sensitive conversations — this self-contained device never sends your voice to the cloud. The full build is open source, so you can follow along or ask an agent to guide you through the setup.
