# Voice cloning

> Turn a short recording into an Aero TTS voice of your own, usable only in your workspace.

Open **Text To Speech → Voice Cloning** and choose **Add your voice**.

1. **Details:** give it a name, choose the language the recording is spoken in, and optionally a gender. Confirm that
   you have the right to clone this voice.
2. **Sample:** record with your microphone or upload a file of **5 to 30 seconds**.
   * Use one person, speaking clearly, in a quiet room. About 15 seconds is best.
   * Files can be WAV, MP3, M4A or WebM, up to about 2.8 MB. A long WAV is usually larger than that, so use MP3 or M4A.

The voice is ready in under a minute. It plays a short preview on its card, and appears under **My Cloned Voices** in
Text to Speech and Conversation.

## Who can clone

* **Owners and admins:** only they can add or remove a voice, because a cloned voice is a real person's voice, kept
  with a record of who agreed to its use.
* **Every member:** can listen to the voices and use them.

## How many

* **Your plan sets the number:** 25 on pay as you go, 50 on Pro, 100 on Scale, and custom on Enterprise.
* **Making room:** remove a voice to free its place.

## What we keep

* **The record:** the recording, the exact consent text and who agreed are kept with the voice.
* **Removing a voice** deletes the voice, its recording and its preview.

> [!NOTE]
>
> **These voices are separate from the Voice Clone page for agents' calls.** That page clones on a different engine.
> A voice made here is for Aero TTS: the console and the API.
