Evaluation of Text-to-Speech synthesis quality on the hard subset of the CV3-Eval Monolingual Chinese dataset, measured using Word Error Rate (WER).

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.

| Scope | Recorded value |
| --- | --- |
| Task | Text-to-Speech |
| Dataset (including any stated split) | CV3-Eval Monolingual (hard-zh) |
| Metric | WER (%) |
| Unit | PERCENT |
| Direction | Lower is better |
| Results loaded | 7 of 7 |
| Coverage | All results currently returned for this benchmark |

Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol.

## Metrics

- [WER (%)](<https://www.sota2.com/research/sota/text-to-speech-on-cv3-eval-monolingual-hard-zh.md?metric=WER%20(%25)>): Lower is better; unit: PERCENT.
