# Voice Agent Overview

> Add Beyond Presence avatars to your existing voice agents.

Most modular solution for technical teams.
Send audio from your voice agent, receive avatar video streams with **250 ms response times** from audio input to HD avatar video output.

## When to Use This

Choose speech-to-video when you need:

* **Component-Level Control**: Complete management of turn detection, STT, LLM, and TTS components
* **Complex Tool Calling**: Flexible LLM integrations with external APIs and databases
* **Voice Infrastructure Migration**: Seamlessly upgrades existing voice agent infrastructure

For zero-infrastructure deployment, use [Managed Agents](/integrations/web) instead.
