Voice Agent delivery controls

Location: Voice Agents → select an agent → Advanced Settings

Voice Agents support controls that shape delivery during a call.

  • Add up to nine additional voices, with labels and optional guidance for when each should be used.
  • For V3 Conversational voices, select Creative, Natural, or Robust voice style presets.
  • Choose whether to use default personality instructions or only your configured prompt.
  • Supported audio‑tag and voice‑setting limits are validated before saving.

Open a Voice Agent, expand Advanced Settings, configure the available options for the selected model family, save, and preview a call.
