Evaluation of Chinese-to-English Speech-to-Speech Conversation performance on the BELLE eval S2S dataset, measured using metrics such as GPT Score and ASR Error Rate.

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 | Chinese-to-English Speech-to-Speech Conversation |
| Dataset (including any stated split) | BELLE eval S2S |
| Metric | GPT Score (T) |
| Unit | SCALAR |
| Direction | Higher is better |
| Results loaded | 2 of 2 |
| 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

- [GPT Score (T)](<https://www.sota2.com/research/sota/chinese-to-english-speech-to-speech-conversation-on-belle-eval-s2s.md?metric=GPT%20Score%20(T)>): Higher is better; unit: SCALAR.

- [GPT Score (S)](<https://www.sota2.com/research/sota/chinese-to-english-speech-to-speech-conversation-on-belle-eval-s2s.md?metric=GPT%20Score%20(S)>): Higher is better; unit: SCALAR.

- [ASR Error Rate](<https://www.sota2.com/research/sota/chinese-to-english-speech-to-speech-conversation-on-belle-eval-s2s.md?metric=ASR%20Error%20Rate>): Lower is better; unit: PERCENT.

- [Off-Target Rate (T)](<https://www.sota2.com/research/sota/chinese-to-english-speech-to-speech-conversation-on-belle-eval-s2s.md?metric=Off-Target%20Rate%20(T)>): Lower is better; unit: PERCENT.

- [Off-Target Rate (S)](<https://www.sota2.com/research/sota/chinese-to-english-speech-to-speech-conversation-on-belle-eval-s2s.md?metric=Off-Target%20Rate%20(S)>): Lower is better; unit: PERCENT.
