## Model description |
|
|
|
We fine-tuned a wav2vec 2.0 large XLSR-53 checkpoint with 842h of unlabelled Luxembourgish speech |
|
collected from [RTL.lu](https://www.rtl.lu/). Then the model was fine-tuned on 14h 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 the same domain. |
