We decided to use vapi voices since they sound great and we assumed that they would perform the best since they are vapi native. However we've been having a lot of random issues with these voices compared to other providers like 11labs, where the voice pitch would change or it just uses a completely different voice all together in the middle of a conversation. Here's a call id that has both of the issues. ba6e2f72-ab79-42cc-8298-a57dfcf5c8d5 Now the problem is that in the call logs it's not possible to see if a voice has changed, or the reason of the change. So we cannot debug this and we are unable to provide these voices to our customers because the issues happen too often. Please investigate.

Try add the

fallbackPlan

property in your assistant's voice configuration..

I'm aware of that feature, but how does it help with our issues. - Random high pitches from vapi voices, much more often than other voices - Main (vapi) voice failing relatively often - Failed voice output not logged in the call logs.

It's helps by automatically switching to stable voices when pitch distortions or failures occur, ensuring call continuity..

We removed the voices, it would just keep switching to a low quality male voice, regardless of fallback plan. Impossible to offer this to clients. Like I sad the vapi voices fail much more often than other providers. What makes it difficult as well is that it's not possible to see in the call logs when or why a fallback plan has been chosen. This particular voice Lily has had issues for months, we're not the only ones: https://discord.com/channels/1211482211119796234/1372230737297801339 https://discord.com/channels/1211482211119796234/1366900107479482398 I understand you must be overwhelmed with supports requests and we don't have a support contract, but just ignoring the issue at hand like this is very disappointing.
