Feel free to tag @AI Evy with additional questions. I also appreciate feedback, it helps me improve.

### Answer I don't have specific information in the available sources about the "Helpful French Lady" Cartesia voice or error messages when selecting voices. The documentation mentions that Cartesia is a supported TTS provider and that you can find available voices in the Dashboard, but it doesn't detail specific voice availability issues or error troubleshooting. [(1) ]() Since this worked yesterday and is now showing an error, this could be a temporary service issue with the Cartesia voice provider. I recommend: - Trying a different Cartesia voice temporarily to see if the issue is specific to that voice - Checking if fallback voices are configured using the

fallback_voice_ids

parameter—this allows the system to use alternative voices from different TTS providers when one is experiencing outages Check out these potentially useful sources: - [Update Voice Agent]() For this specific error, you may want to reach out to Retell AI support directly as they can investigate whether there's a provider-side issue with that particular voice.
