# What is an AI voice agent?

> An AI voice agent is software that holds a real phone conversation on its own. It understands what the caller says, replies naturally in spoken language, and takes an action such as booking an appointment, qualifying a lead or answering a question, without a human on the line.

## How an AI voice agent works

During a call the agent listens to the caller, understands what they mean, decides the right reply from the business brief it was given, and speaks it in a natural voice, while the phone network carries the call. Good agents do this with under a second of delay so the conversation feels normal. See [latency](https://agents.elevatebox.in/glossary/latency).

## What businesses use them for

- Calling new leads within seconds so none go cold
- Confirming appointments and cutting no-shows
- Qualifying enquiries before a human sales call
- Answering common questions 24/7

> In India the hard part is not the English demo, it is a natural call in Telugu, Hindi or a mix. See [the best AI voice agents for Indian languages](https://agents.elevatebox.in/best/ai-voice-agent-telugu).

## Frequently asked questions

### Is an AI voice agent the same as an IVR?

No. An IVR plays menus and asks you to press buttons. An AI voice agent has a real conversation and understands free speech.

### Can an AI voice agent speak Telugu and Hindi?

The good India-first ones can, naturally and in a mix. Many global tools only do English well.
