I have been using the voice ID 15a9cd88-84b0-4a8b-95f2-5d583b54c72e from Catesia, and today I received an error stating that the voice is no longer available. Could you please let me know whether this voice will be available for my use again?

Hi,
Thanks for reaching out. Unfortunately, this voice (15a9cd88-84b0-4a8b-95f2-5d583b54c72e) has been removed from Cartesia's voice catalogue on their end, which is why you're seeing the error.

This isn't something we can restore - Cartesia manages their voice library directly.

To get back up and running, you'll need to switch to a different Cartesia voice:

Browse available voices at https://play.cartesia.ai
Find a voice you like and copy its voice ID
Update your assistant config with the new voice ID

Your existing completed calls are unaffected - this only impacts future assistant saves and calls.

Let us know if you need any help picking a replacement.
