## 🏆 Leaderboard
Vote to help the community determine the best text-to-speech (TTS) models.
The leaderboard displays models in descending order of how natural they sound (based on votes cast by the community).
Important: In order to help keep results fair, the leaderboard hides results by default until the number of votes passes a threshold. Tick the `Reveal preliminary results` to show models without sufficient votes. Please note that preliminary results may be inaccurate.
