Voice AI Template

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.

Frequently asked questions

What is Voice AI Agents?

Who should use Voice AI Agents?

Use Voice AI Agents if you are a Next.js developer, AI product builder, applied AI engineer, or founder looking for an open-source AI app starter instead of rebuilding the same AI interface and server route from scratch.

Is Voice AI Agents production-ready?

This starter is production-grade in its AI safety baseline: prompts are hardened against prompt-injection attempts, provider calls stay server-side, unsafe inputs are constrained, and client-facing errors are kept safe. You should still expand it for your use case by adding or adapting authentication, tenant isolation, persistent storage, observability, quotas, billing, and business-specific policy checks before a real launch.
