Voice Catalog

Use the voice catalog to inspect which voices are available for outbound phone calls. The current SDK exposes catalog listing and filtering; call creation uses the selected tier plus the agent’s configured voice pipeline.

List voices

Filters

The catalog supports these optional filters:
FilterValues
tierbasic, premium
gendermale, female, neutral
languageBCP-47 language code, such as en-US

Place a call

The public SDK call creation surface accepts to, optional agentId, tier, greeting, and optional fromNumber.
Per-call voiceId, voiceSettings, and custom systemPrompt fields are not part of the current public SDK call input. Configure persistent agent behavior in the agent/voice pipeline, and use greeting for the opening line.
