Real-time Voice AI Agents We are open-sourcing the easiest way for developers to build real-time Voice Agents and Virtual Avatars into any app—telephony, web, mobile, robotics, wearables, and beyond.
👋 Hey Product Hunt, I’m Arjun, co-founder of VideoSDK.
I'm beyond excited to launch our Open-Source AI Voice Agent SDK.
Today, voice is becoming the new UI. We expect agents to understand us, respond instantly, and work seamlessly across web, mobile, and even telephony. But, to achieve this, developers have to stitch together: STT, LLM, TTS, glued with HTTP endpoints and, a prayer.
This most often results in agents that sound robotic, hallucinations and fail in product environments without observability.
So we built something to solve that: End-to-End infrastructure to build, deploy, and monitor your AI Voice Agents
Here’s what it offers:
Global WebRTC infra with <80ms latency
Native turn detection, VAD, and noise suppression
Modular pipelines for STT, LLM, TTS, avatars, and real-time model switching
Built-in RAG + memory for grounding and hallucination resistance
SDKs for web, mobile, Unity, IoT, and telephony — no glue code needed
Agent Cloud to scale infinitely with one-click deployments — or self-host with full control
Think of it like moving from a walkie-talkie to a modern cell towers that handles thousands of calls.
VideoSDK gives you the infrastructure to build voice agents that actually work in the real world, at scale.
I'd love your thoughts and questions! Happy to dive deep into architecture, use cases, or crazy edge cases you've been struggling with.
