Hello, I am experiencing an issue when selecting the “French conversational lady” voice from Cartesia in the assistant’s Voice Configuration. Important note: when I click “Talk to Assistant”, the voice works correctly and audio is generated as expected. However, when I click "Publish", the error occurs. This issue happens only with this specific voice. All other Cartesia voices work correctly both in test mode and after publishing. When I click on the "Publish" button, I receive the following error message (see attached screenshot): Couldn't find Cartesia Voice: a249aeff-1e96-4d2c-b23b-12efa4f66f41. Tip: If this is a custom voice, ensure you're using your Cartesia credentials. This is not a custom voice, so I believe this is a bug related to the publishing process or voice resolution for this specific Cartesia voice. Thank you in advance for your assistance. https://cdn.discordapp.com/attachments/1462109989253415005/1462109990495064064/image.png?ex=698b520a&is=698a008a&hm=9b344d54d18594ce9aa3de77d61a37c59152de983abb416d475b58bee274621d& https://cdn.discordapp.com/attachments/1462109989253415005/1462109991149506610/image.png?ex=698b520a&is=698a008a&hm=5a085326a796c2f279fe8dc51d47b3e052cd553b9bc20bee9a4e7a4f2b0ab077&

Thanks for sharing this, since the voice works in test but breaks on publish, this almost always points to a voice ID sync or permission issue between Vapi and Cartesia, not something you did wrong. It’s likely that specific voice ID isn’t resolving correctly at publish time. Re-syncing voices or manually pasting the ID usually fixes it. I can help you confirm what’s happening on your side. Are you using a personal Cartesia API key or a shared/team one? @tancfire

Hello, I didn't use any Cartesia API key. I already tried to copy/paste the voice ID manually in the voice configuration, but the field go back automatically to the list (it probably detects the ID voice as one of the list). I don't know what you mean by re-syncing the voices. Can you provide me the steps to do that ?

Since you’re not using an API key, the issue is likely with how Vapi is resolving that specific Cartesia voice in the publishing workflow. When I mention “re-syncing,” I mean refreshing your Vapi dashboard so it fully pulls the latest list of voices from Cartesia — this often fixes cases where a voice is in the dropdown but can’t be published. I can walk you through the exact steps privately and help make sure this voice works properly when you publish. Would you like me to guide you through it step by step? @tancfire

Oh, ok. I already refreshed my browser (CTRL+F5), close/re-open the browser and the error was still here.m, unfortunetly.

Hi, It seems that the voice (a249aeff-1e96-4d2c-b23b-12efa4f66f41) was removed from Cartesia (https://play.cartesia.ai/voices?q=a249aeff-1e96-4d2c-b23b-12efa4f66f41). Please use another voice instead.
