Cartesia recently added support for Dutch and several other languages to their multilingual API, but they haven’t updated the documentation yet. The support is available in both the playground and the API. However, when I try to use the Vapi API and select "nl" for the language, I encounter the following error: "Failed to create call: {"message":["assistant.voice.language must be one of the following values for sonic-multilingual model: de, es, fr, ja, pt, zh"],"error":"Bad Request","statusCode":400}". This suggests that Dutch isn't supported yet within the Vapi API. Could you please add "nl" to the API?

@Dinand I'm glad to hear about your interest in using Dutch with the VAPI. However, as per the context provided, you no longer need to specify the language when configuring the voice assistant. Instead, you should choose a voice that supports Dutch directly from your voice provider. To resolve the issue you're encountering, please select a voice from your provider that has support for Dutch and use that voice when setting up or modifying your voice assistant. If you're unsure which voice to choose, you may need to check with your voice provider for the available options that support Dutch. If you've already selected a Dutch-supported voice and are still facing issues, or if you need assistance in selecting the appropriate voice, please let me know, and I'll be happy to help further!

With cartesia as the voice provider i do actually have to provide the language because otherwise the voice sounds very much like an american trying to speak Dutch.

@Dinand add to the feature request list.
