### Answer The available information sources cover Voice Agent API operations (create, get, update, list) , but I don't have documentation about a "delete voice" endpoint in these sources. If you're asking about deleting a Voice Agent, that endpoint exists but isn't included in the sources I have access to right now. If you're asking about deleting a custom voice you've cloned or created, I don't have that information in my current sources. Check out these potentially useful sources: - [Get Voice Agent]() - [Create Voice Agent]() - [Update Voice Agent]() Would you like me to try to answer generally, or could you clarify whether you mean deleting a voice agent or a custom voice?
