Voices tab in Building Blocks (light mode)
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.
  2. Per-POC voice assignment — which voice each Phone or Web POC uses, set on the Points of Contact > Edit > Variants tab.
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:
1

Open the POC

Navigate to Agent > Points of Contact, find the POC, click Edit.
2

Switch to the Variants tab

The first variant (A) is selected by default; create more variants for A/B testing different voices.
3

Pick a voice

Use the Voice dropdown to select from the catalog.
4

Save

Submit the variant changes; the new voice applies to subsequent calls.

​
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.
