# AI Agent

## Overview

The unique benefit of the AI Agent is their ability to allow businesses to be available 24 hours a day, without the need for human operators. This means businesses **never** miss a customer, lead, and opportunities as the AI Agent is always ready to serve.

AI Agent can handle calls 24 hours a day. Just provide them with instructions and let them do the work for you.

## No awkward pauses

It is our commitment to build reliable and swift AI Voice.

* no awkward pauses or latency above 500 ms
* and absolutely no space for surprises (unless that's what you enable by design).&#x20;

That's why we only use [Async streaming STT and TTS](/features/async-streaming-stt-and-tts.md)  and why we integrate only the best speech streaming and recognition technology into a VoIP stack, and directly on a media switch.

This is very different from many vendors, who build on top of other (and not async) available solutions. If it is not async, a delay before you hear agent speaking is increased, often in range of 1.5 - 3 seconds, and this delay is not predictable and not capped: the more text to speak agent has the longer it takes to produce that speech (while you hear silence).

You can listen on this page to a few samples of agents running on Microsoft (async STT) / Microsoft (async TTS):

* Polish 🇵🇱
* French 🇫🇷
* English 🇬🇧

## Multilingual

Your agent can operate in any language and it can even run parts of the process in different languages. For instance you can configure agent to accept speech in one language and output speech (voice of the agent) in another one.  [AI Agent](/components/ai-agent.md#ai-inference) may be running in yet another language.

## Choice of LLM models

Whether it's Llama, Gemma or DeepSeek we got you covered. Stick to battle tested Llama 3 or Gemini or select Llama 4 scout (or Llama 4 maverick) for best performance.

## Voices

Select from 1k+ voices across 160+ languages.
