Real-time translation has become essential, yet many solutions rely on cloud infrastructure. But what happens when you’re traveling through areas with poor connectivity or when privacy is paramount? This is where Google‘s Gemma Translator comes into play—a groundbreaking device that operates entirely offline.
The Gemma Translator is a compact handheld device utilizing a Raspberry Pi 5. It processes voice translations on-device, eliminating the need for the internet after initial setup. Free from dependency on cloud servers, it ensures your conversations remain both private and uninterrupted.
Hardware built for accessibility with Google’s Gemma Translator
This device integrates an 8 GB Raspberry Pi 5, a 480×320 touchscreen, microphone, speaker, push-to-talk buttons, and a rotary encoder—all housed within a bold yellow and black 3D-printed case. The design files are open-source, allowing anyone with a 3D printer to recreate it.
Efficient offline processing
The software stack is where the true innovation lies. It runs the Gemma Translator using the Gemma 4 E2B model via LiteRT-LM, achieving efficient translation speeds while using minimal RAM. With Moonshine for speech recognition, you get processing up to five times faster than alternatives like Whisper Tiny, coupled with Kokoro for text-to-speech.

Optimized for real conversations
Designed for direct interactions, two modes allow ease of use whether one person manages both sides or two individuals handle their own microphones and language settings. This translator’s tactile physical buttons enhance usability for conversational scenarios.
A practical privacy promise
Its offline capability isn’t just about privacy—it’s about practicality. For field researchers, travelers, and professionals in sensitive environments, this device offers a reliable translation solution that functions without relying on a network.
