Self-supervised speech model performance with Flemish Dutch pre-training in out-of-domain tasks

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: What is the impact of increasing the amount of Flemish Dutch pre-training data on the word error rate (WER) of self-supervised speech models when evaluated on out-of-domain (e.g., legal, technical) speech recognition tasks compared to English pre-trained models?
