What happened
On 30 September 2026, Hugging Face launched the Open TTS Leaderboard for scalable evaluation of multilingual TTS and voice cloning. It evaluates open-source TTS models using objective metrics, shortening evaluation from weeks of voting to hours. It uses Qwen3 ASR to calculate WER/CER, measures RTFx and TTFA on an H200 GPU, and computes speaker similarity SIM with WavLM embeddings, supporting multilingual and voice-cloning comparisons.
