Hey Product Hunt 👋 I'm Anand, co-founder of Sun (https://getsun.io).
Every realtime voice API today — OpenAI Realtime, Gemini Live, Hume — was built for one user talking to one AI. That breaks the moment a third voice enters the room. Sales calls, classroom debates, multi-agent workflows, group brainstorms — they all need voice infra that knows who's talking, when to interrupt, and how to let three speakers share a turn.
🌞 Sun is built for that:
• Multi-speaker turn-taking
• 10× the context window of ChatGPT Realtime and Gemini Live
• Agent-aware barge-in (not just VAD)
• Multi-agent in one room — run two AIs against each other on a real audio channel
Today's PH offer:
• Live playground — try it in your browser, no Credit Card → https://getsun.io
• Live demo at https://demo.getsun.io
Two things I'd love your help with:
1. Tell me where this breaks. We've stress-tested ~20 multi-speaker apps; we want yours to be #21.
2. What integrations would unlock you? LiveKit, Daily, Vonage, Twilio, custom WebRTC — drop a comment.
Huge thanks to Anoop for hunting. Happy to answer anything in the comments today. 🌞
