Cross-lingual transferability of self-supervised speech models pre-trained on Flemish Dutch, Swiss German, and Luxembourgish

Recent research in speech processing exhibits a growing interest in unsupervised and self-supervised representation learning from unlabelled data to alleviate the need for large amounts of annotated data. We investigate several popular pre-training methods and apply them to Flemish Dutch. We compare off-the-shelf English pre-trained models to models trained on an increasing amount of Flemish data. We find that the most important factors for positive transfer to downstream speech recognition tasks include a substantial amount of data and a matching pre-training domain. Ideally, we also finetune

Research goal: How does the cross-lingual transferability of self-supervised speech models pre-trained on Flemish Dutch compare to those pre-trained on Swiss German or Luxembourgish when fine-tuned on a high-resource Germanic language like German?
