Evaluation of Automatic Speech Recognition performance on the test split of the Spanish CallHome LDC96S35 corpus, typically 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 | Automatic Speech Recognition |
| Dataset (including any stated split) | Spanish CallHome LDC96S35 (test) |
| Metric | WER (%) |
| Unit | PERCENT |
| Direction | Lower 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

- [WER (%)](<https://www.sota2.com/research/sota/automatic-speech-recognition-on-spanish-callhome-ldc96s35-test.md?metric=WER%20(%25)>): Lower is better; unit: PERCENT.

- [Latency (s)](<https://www.sota2.com/research/sota/automatic-speech-recognition-on-spanish-callhome-ldc96s35-test.md?metric=Latency%20(s)>): Lower is better; unit: TIME.

- [Relative Speed-up](<https://www.sota2.com/research/sota/automatic-speech-recognition-on-spanish-callhome-ldc96s35-test.md?metric=Relative%20Speed-up>): Higher is better; unit: SCALAR.
