Impact of Pre-training Data Volume on Cross-dialectal Robustness in Flemish Dutch Self-supervised ASR Models

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 varying the amount of pre-training data on the cross-dialectal robustness of self-supervised models for Flemish Dutch, measured by WER on downstream automatic speech recognition tasks?
