Sun launches collaborative voice API for multi-speaker real-time interactions
By
John
Summary
Sun is a collaborative voice API designed for multi-speaker real-time interactions, unlike existing voice APIs (OpenAI Realtime, Gemini Live, Hume) that only support one-on-one conversations. It features multi-speaker turn-taking, a context window 10× larger than competitors, agent-aware barge-in, and multi-agent support — making it suitable for sales calls, classroom debates, group brainstorms, and multi-agent workflows.
