We noticed that Aura-2 is currently offering Spanish voices, and we're very interested in this (e.g., aura-2-nestor-es: https://developers.deepgram.com/docs/tts-models). However, we're currently unable to use this voice because VAPI doesn't support it.

You can configure a Deepgram voice in Vapi by specifying the provider and voiceId in your assistant configuration. For example:

json
{
  "voice": {
    "provider": "deepgram",
    "voiceId": "aura-2-nestor-es"
  }
}

Note: Vapi has recently expanded Deepgram voice support, but availability of specific voices like "aura-2-nestor-es" may depend on current platform updates. If you do not see this voice in your dashboard, it may not be supported yet—please check the latest [Vapi documentation](https://docs.vapi.ai/changelog/2025/4/16) or contact support for up-to-date availability.

i tried with this setup "assistantRequestError":"Invalid Assistant.

Aura-2 supports Spanish voices like aura-2-nestor-es, but Vapi currently doesn't allow their use, so you'll need to wait for Vapi to update voice support or use alternatives like Azure Spanish voices in the meantime..
