Voice AI Agents

Voice AI Agents is a polished Next.js template for builders who want to create realtime speech-to-speech agent experiences with the OpenAI Agents SDK. It includes a secure backend route for short-lived Realtime client secrets, browser WebRTC connection, automatic microphone capture and audio playback, live transcript rendering, mute and interrupt controls, typed-message backchannel, local browser tool calls, and handoffs between a host, implementation coach, product strategist, and support guide. Use it for voice copilots, conversational product demos, realtime support agents, guided onboarding assistants, or multi-agent voice interfaces.
