Hey team, running into an issue with Cartesia voice language and hoping someone can help verify this on your end. I'm creating a call via the API and passing

assistant.voice.cartesia.language = "hi"

(Hindi). But it seems like that language config isn't being applied — the voice is still pronouncing names with an English accent and mangling them. For example, if I pass the text "Hi Husen Bhai, How are you?" — it comes out something like "Hi, Huzenberg AI. How are you?" — clearly treating it as English. I tested this in the Cartesia playground directly: - When the transcript language is set to English or Auto-detect → same mispronunciation. - When I manually set it to Hindi → it pronounces perfectly. So the language setting in the Cartesia playground does fix the issue — but it doesn't seem to be getting passed correctly through the Vapi API. Could someone verify whether the

language

field is actually being sent to Cartesia perfectly on your side and working as expected ? API reference I'm using: https://docs.vapi.ai/api-reference/calls/create → request.body.assistant.voice.CartesiaVoice.language Org ID:
