# ElevenAgents

Agents accomplish tasks through natural dialogue - from quick requests to complex, open-ended workflows. ElevenLabs provides voice-rich, expressive models, developer tools for building multimodal agents, and tools to monitor and evaluate agent performance at scale.

## Architecture

ElevenAgents coordinates 4 core components:

1. A fine-tuned Speech to Text (ASR) model for speech recognition
2. Your choice of language model or [custom](/docs/eleven-agents/customization/llm/custom-llm) LLM
3. A low-latency Text to Speech (TTS) model across 5k+ voices and 70+ languages
4. A proprietary turn-taking model that handles conversation timing
