I'm sorry to hear that you're experiencing issues with voice cloning. To use the voice cloning feature within VAPI, it is necessary to sync with a voice provider like 11labs. If you're encountering an error during the syncing process, it could be due to a temporary issue or a step that might have been missed.
Could you please ensure that you have followed these steps?
1. From the Voice Library in VAPI, select 11labs as your voice provider.
2. Click on “Sync with 11labs.”
If you have already done this and are still facing an error, I would recommend checking if there are any specific error messages or codes that could give us more insight into the issue. If the problem persists, please ask support for more info on this, as they might need to look into your account details or the specific error you're encountering.
