voice agent SDK is broader it's full real-time voice infra with STT, LLM, TTS, memory, and RAG built in. You can plug in Resemble, ElevenLabs, etc., and deploy across web, mobile, and telephony with <80ms latency.
There are so many AI frameworks out there that live & die so quickly that I am generally hard pressed to use any of these unless there is some killer feature I absolutely need.
1. Voice infra included OpenAI agents handle logic and memory, but they don’t include real-time audio infra.
VideoSDK gives you:
- <80ms global WebRTC latency
- Built-in turn-taking, VAD, and noise suppression
- Real-time voice across web, mobile, IoT, and telephony
2. Fully modular pipeline No vendor lock-in. Swap STT, LLM, TTS, and avatars. Change models live per user or use case. Want ElevenLabs for tone and OpenAI for reasoning? Easy.
3. Native RAG + memory Integrated long-term memory and retrieval help reduce hallucinations and keep conversations grounded.
4. Scale-ready Deploy globally with one click using Agent Cloud or self-host with full control. Built for production use.
If you're building real-time, voice-first agents that need to work across platforms and scale reliably, this is purpose-built for that.
Happy to dive into your use case if you're exploring options.

I’m Sagar, co-founder of VideoSDK.
I'm beyond excited to share what we've been building: VideoSDK Real-Time AI Agents. Today, voice is becoming the new UI.
We expect agents to feel human, 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.
Now, we are open sourcing it!
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 network tower 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.

We are building AI companions, the tone prompting would be great

Yes, with VideoSDK's Real-Time AI Agents, you can control the TTS output tone, either via prompt engineering (if your TTS provider supports it, like ElevenLabs) or by integrating custom models that support tonal control directly. Our modular pipeline architecture makes it easy to plug in providers like ElevenLabs and pass tone/style prompts dynamically per utterance.
We actually support ElevenLabs out of the box. You can check out the integration details here: https://docs.videosdk.live/ai_agents/plugins/tts/eleven-labs
So if you're building AI companions and want them to sound calm, excited, empathetic, etc., you can absolutely prompt for those tones in real time, or even switch voices or tones mid-conversation based on context or user emotion.
Let us know what you're building. Happy to dive deeper into tone control setups or help debug a specific flow!
