Voice settings

Fine-tune the selected voice’s parameters:
  1. Click the Settings icon next to the voice.
  2. Adjust the sliders in the Voice Settings popup:
​
Stability
slider
Controls how consistent the voice sounds over time. Higher values keep tone and delivery more uniform across responses.Recommended: Set to 0.7 or above for reliable performance.
​
Clarity and Similarity
slider
Adjusts how closely the generated voice matches the original recording. Higher values sound more realistic and detailed, but may be less resilient to unexpected prompts. Lower values smooth the voice slightly, making it better suited for dynamic or ASR-driven content.
  1. Click Done to save changes.

​
Publishing changes

After updating voice settings:
  1. Review your configuration on the Agent Voice page.
  2. Click Publish in the top right corner to apply changes to your live agent.
Voice changes only take effect after publishing. Test your agent after publishing to confirm the new voice sounds as expected.

Disclaimer voice configuration

If disclaimer audio is configured separately, the page provides a link to Channels > Voice > Voice Configuration for those settings.
The Disclaimer voice is optional. If not configured, the Assistant voice handles all agent speech.
