This document covers integrating ElevenLabs voice capabilities with AI agent platforms.
The common architecture for voice AI agents combines:
STT (Speech-to-Text) → Agent Brain → TTS (Text-to-Speech)
(Whisper) (LangGraph, (ElevenLabs)
CrewAI, etc.)
| Framework | Voice Agent Support | Notes |
|---|---|---|
| LangGraph/LangChain | Strong | Native ElevenLabs integration, extensive tutorials |
| Google ADK | Strong | Bidirectional audio/video streaming, announced April 2025 |
| Eino | Orchestration | Go-native framework by ByteDance/CloudWeGo, pair with voice stack |
| CrewAI | Orchestration | Pair with voice stack (STT + TTS) |
| AutoGen | Orchestration | Pair with voice stack (STT + TTS) |
ElevenLabs provides a built-in Agents Platform that can integrate with external agents via WebSocket. This allows plugging in LangGraph, CrewAI, or other frameworks as the "brain" while ElevenLabs handles voice I/O.
The most documented combination for programmatic control:
- LangChain ElevenLabs Integration Docs
- Voice Agents: Building Real-Time Conversational AI with Whisper, Groq, LangGraph and ElevenLabs
- From No-Code to Full Control: Rebuilding ElevenLabs' AI Agent with LangGraph
Use this Go SDK (go-elevenlabs) or the official Python/JS SDKs to build custom integrations with any agent framework.
| Use Case | Recommended Approach |
|---|---|
| Simple voice agents, rapid prototyping | ElevenLabs Native Platform (no-code) |
| Multi-turn dialogues, complex memory | LangGraph + ElevenLabs |
| Multi-agent orchestration | CrewAI/AutoGen + voice stack |
| Go-native, high-performance agents | Eino + ElevenLabs via go-elevenlabs |
| Google Cloud integration | Google ADK with ElevenLabs TTS |
| Full control, custom logic | Direct SDK integration |
For production voice agents (e.g., call center automation):
- Latency: Real-time STT and TTS pipelines need sub-second latency
- Telephony: Integration with phone systems (Twilio, etc.)
- Compliance: Recording consent, data retention policies
- Fallback: Human handoff mechanisms
No agent framework is "plug and play" for enterprise voice—expect to layer STT, TTS, telephony, and compliance components.
- ElevenLabs + Mem0 - Persistent memory across voice conversations
- ElevenLabs + Voiceflow - Visual conversation design
