# Available voices

> How Brilo voices work, which accents you can choose from, and how to hear a voice before you put it on a call.

Brilo gives you a library of voices to choose from, and you pick one per agent. Each voice belongs
to a language and usually to an accent, so choosing a voice and choosing an accent are the same
step. You can hear any voice before you use it, without building an agent first.

## Accents you can choose from

These are the accents available across the voice library. Which ones you see depends on the
language your agent speaks, since each voice belongs to one language.

| Language                  | Accents available                                                                  |
| ------------------------- | ---------------------------------------------------------------------------------- |
| English                   | American, British, Australian, Canadian, Indian, Irish, New Zealand, South African |
| Spanish                   | Castilian Spanish, Mexican Spanish                                                 |
| Other supported languages | The accent native to that language                                                 |

## Hearing a voice before you use it

Every voice has a sample you can play in the dashboard, reading the same short script, so you can
compare two voices fairly. This is worth doing before you go live: a voice that reads well in
isolation can still be the wrong fit for your business.

Listen for three things. Whether the pace suits your callers, whether it says your business name
and your industry's words correctly, and whether it still sounds right after thirty seconds rather
than just in the first line.

For the steps, see [Choose a voice](/agents/choose-a-voice).

## What is not supported

* **Voice cloning is not available.** You cannot upload a recording of yourself or a member of
  your team and have your agent speak in that voice.
* **One voice per agent.** An agent cannot switch voice partway through a call. Run separate
  agents if you need different voices.
* **Voices are tied to their language.** Changing your agent's language changes which voices are
  available, so check your voice again after a language change.

## FAQ

<AccordionGroup>
  <Accordion title="Can I hear the voices without building an agent?">
    Yes. Every voice has a preview sample you can play from the dashboard, reading the same script,
    so you can compare accents and pick before you build anything. See
    [Choose a voice](/agents/choose-a-voice).
  </Accordion>

  <Accordion title="Can I use my own voice, or clone a voice?">
    No. Voice cloning is not available in Brilo, so you choose from the voice library rather than
    supplying a recording. If no voice in the library fits your business, contact
    [support@brilo.ai](mailto:support@brilo.ai) and tell us what you are looking for.
  </Accordion>

  <Accordion title="Which accents can my agent have?">
    English agents can use American, British, Australian, Canadian, Indian, Irish, New Zealand,
    and South African accents. Spanish agents can use Castilian or Mexican Spanish. Other
    languages use the accent native to that language.
  </Accordion>

  <Accordion title="Why does my voice sound different on a real call than in the preview?">
    A phone line carries less of the sound than your computer speakers do, so any voice is a
    little narrower on a real call. Judge a voice by calling your own agent rather than by the
    preview alone. See [Test your agent yourself](/go-live/test-your-agent-yourself).
  </Accordion>

  <Accordion title="Do some voices cost more than others?">
    No. Every voice costs the same, and your call minutes are counted the same way whichever voice
    you choose. See [Plans and what they include](/supported/plans).
  </Accordion>

  <Accordion title="Can two agents use different voices?">
    Yes. Voice is set per agent, so your after hours agent can sound different from your daytime
    one. A single agent uses one voice throughout a call and cannot change it partway.
  </Accordion>

  <Accordion title="Why can I not hear a preview?">
    Check your browser is not muted and that it is allowed to play sound on the dashboard. If the
    preview still does not play, try another browser before contacting support, since it is almost
    always a browser setting rather than your account.
