Language translate during the call for Outbound Calls: These are the languages required for Translation: English (US) English (UK) Spanish (Latin America) Spanish (Spain) Arabic Russian Dutch French German Italian Portuguese (EU) Portuguese (Brazilian) Turkish Polish Romanian Greek Swedish Norway Japanese Hindi Kindly suggest best approach for this.

Best Approach for Multilingual Outbound Call Translation: Set up your assistant to use Deepgram (Nova 2/Nova 3, "Multi") or Google STT ("Multilingual") for automatic language detection, and Azure for voice synthesis with fallback voices for each required language. Here’s a sample configuration snippet:

json
{
  "transcriber": {
    "provider": "deepgram",
    "model": "nova-3",
    "language": "multi"
  },
  "voice": {
    "provider": "azure",
    "voice": "multilingual-auto",
    "fallbackVoices": [
      {"language": "es-ES", "voice": "es-ES-ElviraNeural"},
      {"language": "fr-FR", "voice": "fr-FR-DeniseNeural"},
      // Add other languages as needed
    ]
  }
}

Test your setup to ensure all required languages are supported and adjust fallback voices as needed. [See full multilingual setup guide](https://docs.vapi.ai/customization/multilingual) Source: - [Multilingual support documentation](https://docs.vapi.ai/customization/multilingual)
