Language matrix
The API exposes supported languages and a matrix that helps you pair STT, TTS, and LLM capabilities. Start from the matrix when you design a new agent.Voices
List voices per provider, search catalogs when available, and align voice options with your brand and accessibility goals.Conversation behavior
- Prefer explicit language confirmation when ambiguity is costly (for example finance or healthcare).
- Keep fallback providers configured where the API supports it, so a single provider outage does not drop the call.
