# Automatic Speech Recognition on ATCO2 1-hour (test) Source: [Automatic Speech Recognition on ATCO2 1-hour (test)]() Collection index: [llms.txt]() Data updated: 2026-05-13T08:03:45.213Z Evaluation of Automatic Speech Recognition (ASR) performance on the specific 1-hour test split of the ATCO2 dataset, 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) | ATCO2 1-hour (test) | | Metric | WER | | Unit | PERCENT | | Direction | Lower is better | | Results loaded | 17 of 17 | | 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](): Lower is better; unit: PERCENT. ## Recorded results | Method | WER | Result date | Report paper | | --- | --- | --- | --- | | Whisper-small, BEARD (5381 h) + FT | 17.17 | Not recorded | 69019f813ef7ccd74e5e3afc | | Whisper-small, BEARD (500 h) + FT | 17.53 | Not recorded | 69019f813ef7ccd74e5e3afc | | Whisper-small, BEARD (5381 h) + FT | 17.58 | Not recorded | 69019f813ef7ccd74e5e3afc | | Whisper-small, BEARD (5381 h) + FT | 17.72 | Not recorded | 69019f813ef7ccd74e5e3afc | | Whisper-small, BEARD (5381 h) + FT | 17.87 | Not recorded | 69019f813ef7ccd74e5e3afc | | Whisper-small, BEARD (5381 h) + FT | 18.01 | Not recorded | 69019f813ef7ccd74e5e3afc | | Whisper-small, BEARD (5381 h) + FT | 18.05 | Not recorded | 69019f813ef7ccd74e5e3afc | | Whisper-small, BEARD (5381 h) + FT | 18.06 | Not recorded | 69019f813ef7ccd74e5e3afc | | Whisper-small, BEARD (1000 h) + FT | 18.06 | Not recorded | 69019f813ef7ccd74e5e3afc | | Whisper-small, BEARD (5381 h) + FT | 18.27 | Not recorded | 69019f813ef7ccd74e5e3afc | | Whisper-small, BEARD (5381 h) + FT | 18.4 | Not recorded | 69019f813ef7ccd74e5e3afc | | Whisper-small, BEARD (2000 h) + FT | 18.4 | Not recorded | 69019f813ef7ccd74e5e3afc | | Whisper-small, FT | 19.54 | Not recorded | 69019f813ef7ccd74e5e3afc | | Whisper-small, BEARD (5381 h) + FT | 19.68 | Not recorded | 69019f813ef7ccd74e5e3afc | | XLS-R (FT ATC) + LM | 19.8 | Not recorded | 69019f813ef7ccd74e5e3afc | | Whisper-small, FT | 22.79 | Not recorded | 69019f813ef7ccd74e5e3afc | | Whisper-small, no FT | 63.32 | Not recorded | 69019f813ef7ccd74e5e3afc | ### Whisper-small, BEARD (5381 h) + FT WER: 17.17.
