Rime AI Voices Not Talking in Spanish

Hi,
I'm trying to use Rime.ai's Mist V2 with a Spanish voice through VAPI. I've already selected the Spanish voiceId "isa", but the output still has an English accent. How can I make sure the default language is correctly set to Spanish?

Thanks.

Set the model ID to “mistv2” and explicitly set the assistant’s language to “es-ES”..

Hello, you can check this call: fa61e223-5b06-4cd5-abf6-0df60e062cf9

And you will see that it is not possible to use Rime AI, by the way, when I try to update language via API, it responds with:

"400 - "{\"message\":[\"voice.property languageCode should not exist\"],\"error\":\"Bad Request\",\"statusCode\":400}""
