Video SDK

👋 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.

this looks promising, makes your main product a full stack video & audio framework for building agents.

Congrats on the launch team!

Another amazing launch! Let's go team @arjun_kava1 @sagar_kava

Congrats on the launch. @arjun_kava1 .

Congrats on the launch! 🎉 @Video SDK This looks like a game-changer for voice AI development. The <80ms latency with global WebRTC infrastructure sounds impressive. Quick question - how does your native turn detection handle overlapping speech or interruptions? That's always been a challenge with voice agents. Also curious about the pricing model for the Agent Cloud vs self-hosting options!

Congrats on the launch, team!!! 🥳

For Introducing Voice Agent SDK — an open-source framework to build real-time voice agents that actually work in production.

• Built on VideoSDK, it empowers agents to join meetings, listen, speak, and think — all with under 80ms latency.

• The cascading pipeline supports STT, LLM, TTS, VAD, and Turn Detection — fully provider-agnostic.

• With A2A and MCP, you get multi-agent collaboration and seamless integration with external tools and services.

We can’t wait to see what the community builds with Voice Agent SDK — go create something amazing!

Video SDK's AI Voice Agent SDK with its low - latency infrastructure and modular pipelines is a great help for developers building real - time voice applications! For developers who want to integrate custom AI models into the SDK, does Video SDK's AI Voice Agent SDK support easy integration of custom models?
