Hugging Face releases Open TTS Leaderboard for objective evaluation of multilingual TTS and voice cloning
Hugging Face released Open TTS Leaderboard, which uses objective metrics including WER/CER, RTFx, TTFA, and speaker similarity to evaluate open-source TTS models, reducing evaluation cycles from weeks of voting to hours.
Why it matters: Hugging Face replaces vote-based evaluation with objective metrics, showing how to compare open-source TTS models across languages and voice cloning.
