DogeHouse Babel is a live voice chat room where everyone speaks their own language and hears everyone else in theirs. A Claude Opus 4.8 interpreter joins the room as a participant, listens to each speaker, and translates in real time — speaking each translation aloud into every listener's own language on a separate per-language audio track, and showing live captions. It goes beyond literal translation: Opus 4.8 reasons over conversational context, so it catches cross-language misunderstandings (e.g. someone hearing the Spanish 'las tres' / 3 o'clock as a headcount of 3 people) and interjects to clarify, and it answers questions addressed directly to it. Built on a revival of the open-source DogeHouse. Stack: Next.js + LiveKit (WebRTC rooms) + Claude Opus 4.8 (interpreter brain) + Groq Whisper (speech-to-text) + OpenAI TTS, with an always-on Node agent worker.
