Model description
We pre-trained a wav2vec 2.0 base model on 842h of unlabelled Luxembourgish speech collected from RTL.lu. Then the model was fine-tuned on 4h of labelled Luxembourgish Speech from the same domain. Additionally, we rescore the output transcription with a 5-gram language model trained on text corpora from RTL.lu and the Luxembourgish parliament.
