Right now Vapi’s native built-in voice options are very limited essentially 3 active voices (Rohan, Elliot, Savannah) which is why none of the 6 you tested matches Kylie. Kylie and other older voices are legacy and aren’t supported for new/published agents. If you want something closer to Kylie’s sound, we can switch the agent to use a third-party provider voice (like from ElevenLabs) or hook up a custom TTS voice that fits your style better. That gives you a much larger voice library than what’s available by default in Vapi’s built-in set. @pro1710
