The synthetic voice an AI agent uses on phone calls (and on voice-enabled web chats) is configured in two places:

1. **The voice catalog** — every voice available to your tenant. Managed under [Building Blocks > Voices](/building-blocks#voices).
2. **Per-POC voice assignment** — which voice each Phone or Web POC uses, set on the [Points of Contact > Edit > Variants tab](/points-of-contact#variants).

This page is the operator's guide to both.

## The voice catalog

Navigate to **Build > Building Blocks > Voices** to see every voice configured for your tenant.

Each voice has:

* **Display Name** — what shows in dropdowns (e.g., "Clara").
* **Description** — voice characteristics (e.g., "Female, Multilingual, Fast").
* **Sample** — a play button to preview the voice with the configured sample text.
* **Download** — save the sample audio to disk.

### Previewing voices

Click the play button on any row. The sample plays with whatever text you've configured via **Voice Sample** at the top of the page.

### Editing the sample text

Click **Voice Sample** to change the text that previews use. Useful for hearing specific brand phrases, customer-facing names, or terminology your agent will actually say.

### Adding and removing voices

* **Create** — add a new voice from the supported voice catalog.
* **Delete** — remove a voice. Any POC currently using the deleted voice falls back to the tenant default.

## Assigning a voice to a POC

A voice is selected per Variant on a Phone or Web POC:

<Steps>
  <Step title="Open the POC">
    Navigate to **Agent > Points of Contact**, find the POC, click **Edit**.
  </Step>

  <Step title="Switch to the Variants tab">
    The first variant (`A`) is selected by default; create more variants for A/B testing different voices.
  </Step>

  <Step title="Pick a voice">
    Use the **Voice** dropdown to select from the catalog.
  </Step>

  <Step title="Save">
    Submit the variant changes; the new voice applies to subsequent calls.
  </Step>
</Steps>

## Tips

* **Match voice to brand.** A clinical hospital line wants a different voice than a casual retail line. Listen to a few options with realistic sample text before deciding.
* **Test multilingual voices on multilingual flows.** Some voices speak only one language well; pick a clearly multilingual voice if your flow handles `Multilingual` as a language setting.
* **A/B test before standardizing.** Use Variants on a Phone POC to split traffic across two voices and compare downstream metrics (handle time, customer satisfaction proxy).
* **Re-sync sample text after major copy changes.** When you update the agent's standard greeting, update the Voice Sample to match — easier to evaluate voices against words you actually use.
