| # TTS Robustness Benchmark |
|
|
| ## Overview |
| The **TTS Robustness Benchmark** is a set of evaluation samples used to calculate domain-wise CER (Character Error Rate) scores across 7 critical stress-test categories. This benchmark ensures that each sentence-language pair appears exactly once, providing a clean and reliable metric for TTS robustness. |
