# Custom voice

> Commission a brand-exclusive custom voice for enterprise accounts.

Enterprise customers can commission a custom voice built from recorded samples of a specific speaker, giving your agent a unique, brand-specific sound that only your organization uses.

## What custom voices offer

* **Brand-exclusive voice** – A synthetic voice trained on recordings of a specific speaker, available only to your organization.
* **Consistent identity** – The same voice across all calls, environments, and languages (where supported).
* **Fine-tuned characteristics** – Control over tone, pace, and delivery style during the cloning process.

## Requirements

* An active PolyAI enterprise account.
* High-quality audio recordings of the target speaker (PolyAI provides recording specifications).
* Legal clearance from the speaker to use their voice for synthesis.

## How to request

1. Contact your PolyAI account manager or representative.
2. PolyAI provides a recording brief with duration, format, and content requirements.
3. After recordings are submitted, the voice is trained and made available in your [Voice Library](/voice/voice-library).

<Note>Custom voice creation typically takes 2-4 weeks depending on recording availability and review cycles.</Note>
