Google open-sources a Gemini Live real-time translation app on LiveKit, one shared session per language

Phil Schmid highlights Google's official open-source project gemini-live-translate-livekit: a real-time broadcast translation app built on the Gemini Live API + LiveKit. An organizer speaks into a mic, attendees pick a language and hear live AI translation; each language spins up exactly one Gemini Live API session shared across all listeners of that language.

Architecture: organizer publishes audio to a LiveKit room → a TranslationBridge bot per language joins and subscribes → Gemini Live API's translationConfig handles directional translation → translated audio is published back to LiveKit → attendees subscribe to the translator-{lang} track. Full code and docs are available to deploy yourself.
