Voice settings allow you to customize how your agent sounds during conversations. These settings affect all calls unless overridden via the API.

​
Language

The primary language your agent will use for conversations. This setting should align with your agent’s prompt and intended use case. Currently supported:

  • English
  • Spanish

When setting up your agent’s prompt, make sure to explicitly mention the chosen language to ensure consistent behavior.

​
Default Voice

Select the voice that your agent will use by default. Each voice has been optimized for natural conversation and clear pronunciation, and certain voices have been optimized for spelling. For more information on voices, check out the Voices page.

The default voice can be overridden on a per-call basis using the API if needed.

​
Volume

Fine-tune your agent’s speaking volume to ensure optimal audio levels for different scenarios. The volume scale includes:

  • Quietest
  • Quieter
  • Normal (recommended default)
  • Louder
  • Loudest

This setting is particularly useful when your agent needs to adapt to different environmental conditions or caller preferences.

​
Pronunciation Config

Customize how your agent pronounces specific words or phrases. This is especially useful for:

  • Brand names
  • Product names
  • Technical terms
  • Industry-specific terminology
  • Location names

Pronunciation configurations are applied globally to all of your agent’s conversations.
