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.
