# Introduction

> Integrate real-time talking avatars into your voice AI pipeline

## Overview

Agent Human provides native integrations for the two most popular real-time voice AI frameworks — **Pipecat** and **LiveKit Agents**. Both integrations handle all the complexity of session management, audio streaming, and video delivery so you can add a talking avatar to your pipeline with just a few lines of code.

## Choose Your Integration

  <Card title="Pipecat" icon="plug" href="/documentation/pipecat/overview">
    **`AgentHumanVideoService`** — slots into any Pipecat pipeline right after your TTS service. Sends TTS audio to the avatar and injects the avatar's video frames back into your pipeline.
  </Card>

  <Card title="LiveKit Agents" icon="signal" href="/documentation/livekit/overview">
    **`AvatarSession`** — drops into your LiveKit Agents entrypoint and renders your agent's voice output as a talking avatar video in the LiveKit room.
  </Card>
</CardGroup>

## How It Works

Both integrations follow the same underlying flow:

1. **Create a session** — the integration calls the Agent Human REST API to provision an avatar server
2. **Stream audio** — your pipeline's TTS audio is forwarded to the avatar server in real time
3. **Receive video** — the avatar server generates synchronized talking-head video and publishes it to your video room

You never need to manage sessions, tokens, or audio encoding manually — the integration handles all of it.
