### Answer When adding a custom voice from Eleven Labs or any other provider, ensure you accurately update the

voice

property in your assistant configuration. For custom voices, the configuration should include the

provider

and your specific

voiceId

. If you're using Eleven Labs, your configuration might look similar to this:

json
{
  "voice": {
    "provider": "elevenlabs",
    "voiceId": "your-custom-voice-id"
  }
}

However, the detailed error during publishing is crucial for a precise diagnosis. The issue may not directly relate to using Multilingual v2, but make sure the custom voice ID and provider are correctly specified. For further assistance on specific errors or setup, checking the documentation or reaching out for support might be necessary [(1)]() .
