- What happened
- Hugging Face launched Open TTS Leaderboard, an objective metrics-based evaluation system for multilingual text-to-speech and voice cloning models.
- Why it matters
- Engineers building or selecting TTS systems need standardized benchmarks that scale faster than human preference voting and cover multiple languages.
- Watch out
- Objective metrics like WER and speaker similarity don't measure naturalness or expressiveness directly; they complement but don't replace human preference evaluation.
