OpenAI details how it built its realtime voice AI system

OpenAI published an engineering writeup on GPT-Live, a system for continuous, turnless voice conversations with AI, built in six months using a turnless speech model and a low-latency architecture. The post describes the technical approach behind faster, more natural spoken interaction with AI.

Why it matters: Turnless, low-latency voice architecture is a prerequisite for AI assistants that feel like real conversation partners rather than walkie-talkie exchanges, and OpenAI publishing its approach could accelerate similar builds elsewhere. It also signals voice interfaces becoming a priority axis of competition alongside text and coding capability.
