# Automatic Speech Recognition on CHiME-4 single-channel (et\_simu) Source: [Automatic Speech Recognition on CHiME-4 single-channel (et\_simu)]() Collection index: [llms.txt]() Data updated: 2026-02-26T06:08:31.790Z Evaluation of Automatic Speech Recognition performance on the single-channel simulated evaluation split (et\_simu) 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 single-channel (et\_simu) | | Metric | WER | | Unit | SCALAR | | Direction | Lower is better | | Results loaded | 19 of 19 | | 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: SCALAR. ## Recorded results | Method | WER | Result date | Report paper | | --- | --- | --- | --- | | WavLM (Weighted-sum) + Joint FT.
