Open TTS Leaderboard cuts model evaluation from weeks to hours
Hugging Face’s Open TTS Leaderboard gives multilingual and voice-cloning models a faster, repeatable check instead of waiting weeks for human votes. It runs generated audio through speech recognition for intelligibility, measures inference speed and first-audio latency, and compares speaker embeddings for voice similarity. The process takes a couple of hours, but it does not measure naturalness, expressiveness, or listener preference.
