Evaluation of Text-to-Speech synthesis quality improvement using the Seed-TTS MaskGCT dataset, assessed via subjective and objective metrics including WVMOS, UTMOS, DNSMOS, NISQA, and 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 | TTS Quality Improvement |
| Dataset (including any stated split) | Seed-TTS MaskGCT |
| Metric | WVMOS |
| Unit | SCALAR |
| Direction | Higher is better |
| Results loaded | 5 of 5 |
| 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

- [WVMOS](<https://www.sota2.com/research/sota/tts-quality-improvement-on-seed-tts-maskgct.md?metric=WVMOS>): Higher is better; unit: SCALAR.

- [UTMOS](<https://www.sota2.com/research/sota/tts-quality-improvement-on-seed-tts-maskgct.md?metric=UTMOS>): Higher is better; unit: SCALAR.

- [DNSMOS](<https://www.sota2.com/research/sota/tts-quality-improvement-on-seed-tts-maskgct.md?metric=DNSMOS>): Higher is better; unit: SCALAR.

- [NISQA](<https://www.sota2.com/research/sota/tts-quality-improvement-on-seed-tts-maskgct.md?metric=NISQA>): Higher is better; unit: SCALAR.

- [WER](<https://www.sota2.com/research/sota/tts-quality-improvement-on-seed-tts-maskgct.md?metric=WER>): Lower is better; unit: PERCENT.
