# Automatic Speech Recognition on CHiME-4 (et real) Source: [Automatic Speech Recognition on CHiME-4 (et real)]() Collection index: [llms.txt]() Data updated: 2026-02-26T06:08:31.833Z Evaluation of Automatic Speech Recognition performance on the 'et real' data split of the CHiME-4 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) | CHiME-4 (et real) | | Metric | WER | | Unit | PERCENT | | Direction | Lower is better | | Results loaded | 14 of 14 | | 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 | | --- | --- | --- | --- | | W2T-E | 6.5 | Not recorded | 6984246ba8b01e76cc8ee973 | | WavLM (Weighted-sum) | 6.8 | Not recorded | 6984246ba8b01e76cc8ee973 | | W2W-E (TF-GridNet) | 8.2 | Not recorded | 6984246ba8b01e76cc8ee973 | | W2T-E | 8.2 | Not recorded | 6984246ba8b01e76cc8ee973 | | V2T-E (E-Branchformer) | 8.9 | Not recorded | 6984246ba8b01e76cc8ee973 | | T2T-E | 9.4 | Not recorded | 6984246ba8b01e76cc8ee973 | | V2T-E (TCN) | 9.4 | Not recorded | 6984246ba8b01e76cc8ee973 | | V2T-E (MLP) | 10 | Not recorded | 6984246ba8b01e76cc8ee973 | | W2W-E (TF-GridNet) | 12.4 | Not recorded | 6984246ba8b01e76cc8ee973 | | WavLM | 13.5 | Not recorded | 6984246ba8b01e76cc8ee973 | | W2W-E (Conv-TasNet) | 13.7 | Not recorded | 6984246ba8b01e76cc8ee973 | | WavLM | 17.3 | Not recorded | 6984246ba8b01e76cc8ee973 | | W2W-E (Conv-TasNet) | 19.3 | Not recorded | 6984246ba8b01e76cc8ee973 | | FBANK | 23 | Not recorded | 6984246ba8b01e76cc8ee973 | ### W2T-E WER: 6.5.
