TTS capabilities
What each voice provider can be handed — its languages, and the one model it ships.
Get Tts Capabilities
A different question from which voice you get. No voice choice avoids it: every Cartesia voice fails
the same way on Kannada, because the provider itself cannot be handed the language.
Check What
Each provider ships exactly one voice model, and
languages before pairing a provider with a language you have not used it for, or the agent
is refused with voice_config_invalid.
What model is for
Each provider ships exactly one voice model, and voice.model on an agent is filled in from
voice.provider — you never choose it. This is where the value you read back comes from, and the
only place it is written down.Authorizations
Your API key as a Bearer token, e.g. Authorization: Bearer vk_….
Response
What each voice provider can be handed at all — independent of which voice you pick. Check it before saving an agent: a provider handed a language it cannot speak is refused, and every voice of theirs would fail the same way.
